musicious Seems more and more likely that Tesla will have the most advanced HUD in any car
Recent Tesla hire might have spoiled one of the Model 3�s biggest surprises�
Apr 15, 2016
houdini I like. I like it a lot.�
Apr 15, 2016
Jason Bourne Choosing between an HUD or fully autonomous AP as the two best explanations for lack of dashboard displays, I think it's much more likely to be an HUD. I doubt that Tesla is going to equip all Model 3s with AP as a standard feature (they've only said the safety features will be standard), so not every Model 3 will have AP. So if HUD isn't the reason, what will cars without AP do?�
Apr 15, 2016
Trev Page I think this is happening but probably not in the usual way people think. Tesla will do something very futuristic along with Autopilot.
The Model 3 will look "normal" from the outside but the interior is Tesla's chance to really shine and outdo the competition. When Elon made the comments "I think we will do something radical" in regards to Model 3 last year, we all took it to mean the exterior but now it appears he was talking about the interior and controls. Sneaky guy.�

zenmaster If Tesla does incorporate a HUD, please let it be visible while wearing polarized sunglasses.�

Rockster +1
I frequently need to raise my sunglasses to read displays now.�
Apr 15, 2016
Boourns I think this also conforms to Elon's comments re: Part 2 taking it to the "next level." I expect an advanced HUD system for sure.�
Apr 15, 2016
Brad_NC I really like the idea of a nice HUD... But what does everyone feel like they want in the HUD? Having just returned home from a 1,000 drive (vacation), in a car with no cruise control... I can't think of too much I want in the HUD.
Current speed and posted speed.
Range and distance to nearest SuperCharger (and an arrow to indicate direction to drive to get there).
Nav and lane placement of my car and those around me.�
Apr 15, 2016
Topher It is my thought that EM wants all Teslas to have autopilot (it is part of the master plan). It may be that, at the moment, they need to monetize that decision, but eventually AP will be free (not only for upcoming cars but retro'ed into as many old ones as possible). That means that no model should have any (known) impediments to that conversion. Putting a Autopilot capable HUD into all models ? is in keeping with that (as is including all autopilot hardware).
I know I love saying 'yeah, I planned for that' when adding a new feature to my house. I suspect that the charge Elon Musk will get out of it for a million cars will be even greater.
Thank you kindly.�
Apr 15, 2016
Topher While I agree that minimal information is probably best most of the time, there is a lot of transient information which would be awesome. For example, when you put on the blinker, having a blindspot monitor pop up would be huge. Basically anything which might, in a lesser car, cause you to take you eyes off the road could be displayed momentarily in the HUD. Hopefully they all have their copies of Tufte on their desks. How about having the speedometer color-coded by how far your speed is from posted?
Thank you kindly.�
Apr 15, 2016
xmetal If I could have speed, real-time tracking indicators for traffic around/behind me in blind spots, GPS/driving directions (with an overlay of the directional arrows put onto the real lanes) and maybe some simple media controls (like current song playing, or access to phone functions) that would be rad.�
Apr 15, 2016
McRat HUDs blow on cars. They just take distracted driving to a whole new planet. "Wow, now I can look straight ahead and not see *sugar* before I ram it!" I have 4 cars with it, and everyone is turned off.
But then again, I'm a dork who doesn't need a cellphone to drive either. A relic of the past; someone who believes not hitting *sugar* is the the most technologically advanced method of automotive safety, not the crumple zone.�
Apr 15, 2016
metier Instead of being projected onto the front window, could it not be projected onto the dashboard strip so it would be where the displays are on current cars, and have it 3d effect so it looks like it is farther away to make it easier to focus on it.�
Apr 15, 2016
ecarfan Here is one possible approach Tesla could take with the 3:
The base version for $35K will only have the 15" center display and no AP software (but it will have all the necessary sensor hardware) or other driver side displays. We know from the reveal that center display shows the speed and other basic info in the upper right corner. That will be fine for driving the car in the usual "human controlled" manner. I do not believe that a HUD will be included at the base price, which is amazingly low for a long range (200+ miles) EV that is a mid-size sedan, and a stunningly gorgeous one at that.
If the AP option is purchased it will include a HUD that projects what the AP sees as well as basic info like speed, alerts, and warnings.
In other threads people have posted that there are HUD units that work with polarized sunglasses.
I think it is very likely that the 3 will go into production in late 2017 with all the hardware necessary for fully autonomous driving but the software will not be ready. That will take another year or two.
Just before the 3 goes into production, the S and X will be redesigned to include all the hardware needed for fully autonomous driving. The driver side display will be gone and a HUD will be standard. AP software will still be an option.
At that point all Teslas will be built with full AP hardware. By 2019 or so, fully autonomous AP software will be available as an option.�
Apr 15, 2016
yesup This is the main reason why I don't think HUDs would be standard.
It is a nice gadget as an option to increase the profit margin, but it is not a good way to display important information because of the reason above. There are HUDs which work with polarized sunglasses like DLP, but it would be too expensive.
If Tesla wanted a secondary display in addition to the big screen, they would have retained the instrument panel.
HUDs is NOT a good substitute for a secondary display.
If Tesla decides the center screen is good enough, instrument panel is not necessary, and HUD is not necessary as well.
When you have to keep the cost at $35,000 and you have to make 400,000 cars in a short time, I would cut out all the unnecessary stuff which by itself won't sell the car.
I bet we won't see a HUD in base model.�
Apr 15, 2016
ecarfan If the HUDs you have in your cars (which manufacturers and models?) are lousy that is the fault of the UI design.
Has it occurred to you that perhaps Tesla could design a better UI that would make a HUD a useful driving aid and make driving safer? Or do you believe that your sensory and cognitive processing abilities while driving are superior to any hardware/software combination that could possibly be created? I ask that in all seriousness.�
Apr 15, 2016
03DSG As a retired airline pilot I can tell you polarized sunglasses don't work in cockpits. You can't see the screens and depending on the aircraft and how the cockpit windows are heated you literally can't see out the window. All you see is hashed lines. The bottom line for the majority of pilots, especially in glass cockpits is regular not polarized sunglasses:
Vision in Aviation�
Apr 15, 2016
JamesL Obviously, speed display and turn by turn directions would be great. Any warnings would also be good to have, battery temperature, battery capacity, Tire Pressure sensor, etc.
If you combine some of the decision making parameters for AP, you could have the following:
- Lane position overlay - for low visibility conditions where it is difficult to see the lane lines.
- Augmented Reality overlay for potentially dangerous objects - Pedestrians, deer, rapidly slowing vehicles in front of you, etc.�
Apr 15, 2016
ikjadoon From his tweet, "Wait until you see the real steering controls and system for the 3. It feels like a spaceship."
Meaning, there's something more than just the screen. There's a "system"...�
Apr 15, 2016
palmer_md I imagine most of the tech will be in the Model S long before 3. But as mentioned earlier I don't think any will be included at the base price for 3, perhaps S. It will be a nice option on 3. Is my delivery still 100 months away? I'm not sure I can keep coming here getting teased with all this information for that long.�
Apr 15, 2016
jbcarioca I was one of those who tried polarized sunglasses while flying. At altitude I saw a prison lattice! Only after retiring from high altitude flying I have gone back to ppolarized sunglasses. I hope the Model 3 HUD can somehow fix that. technology has moved far since my experience, so I'm hopeful.�
Apr 15, 2016
BlairC I would not mind a HUD, but I think it is possible they may utilize that black strip along the dash for a secondary display ala the design drawing I've seen from the guy they brought over from Porsche.�

lianregnif all this talk reminds me of Google glass.�
Apr 15, 2016
ttupper92618 I think it is important to remember that the Model 3, and many other cars sold 3 or so years out, will have automated safety features like automatic braking. In fact, virtually every major manufacturer has committed to NHTSA guidelines to integrate automated braking in all cars sold in the US by 2022. The point is that 'not hitting' stuff is going to become something the car helps you do - for all cars - very soon. If one imagines more capable autonomous systems like those clearly being developed by Tesla (and others), then obstacle avoidance could also play into the mix. With systems like that in place, one then has to confront the potential that differentiation in automobiles will start to rest in the domain of user experience, and that's why we see such an emphasis on big beautiful information displays in Tesla products.
If one considers the direction of automation technology, I think it is true that:
- Concerns about the distraction caused by a HUD are overblown.
- What one can or perhaps should do with a HUD in terms of feature and design move well beyond simple information displays for speed, status, etc.
I think it might be interesting to view a HUD not merely as an information display replacing the instrument package... but as an implementation of augmented reality, which would allow it to do / be much more.�
Apr 15, 2016
Lloyd Rather than the windshield, how about using the white area in front of the steering wheel as a projector screen? That allows display of multiple functions over a wide area without an expensive HUD projector!!! Brilliant and Simple!!�
Apr 15, 2016
Kevin Harney I think the HUD display will feature block buster movies because of AP !!�
Apr 15, 2016
el crucero Better yet, how about your remaining distance on charge as a function of current speed?
With regards to the posts above, I have a 2012 Prius plug-in. It has an HUD that was included in the $35,000 package price. The HUD projects at the very lower windshield. It is out of the way but easily visible. It displays speed, power efficiency in a bar graph, and navigation arrows if you have a destination entered (as well as audio commands in a pleasant female voice). It is brighter during the day and softer at night. Works great! I wear "transitions" eye glasses that turn dark when in sunlight and there is no conflict with the HUD. My wife wears polarized clip-ons with her glasses and she can see the HUD fine.
So, in our opinion:
- the HUD in our car is NOT a distraction
- a relatively high tech HUD is possible in a $35K car as standard
- our HUD works great with useful information, it is anything but a gadget
A good HUD, like on a Prius, is essential to us. We hope that it comes standard on the T3, but we will pay extra to get one if necessary.
We also have a primitive AP on our car. It is a radar cruise control that monitors traffic directly ahead only. We have come to depend on it. If the T3 doesn't include this feature, even as an option, that would be a deal breaker for us.�

wycolo Polarized eyeglasses are for reducing reflections off of water or ice as well as glints off of curved shiny surfaces such as cars and buildings.
Not so much of this in the sky for pilots to deal with, it would seem.
In any event the problem presented for earthbound drivers who enjoy polarized lenses is that they likely don't have a pair of non-polarized glasses handy when the need might arise. So HUD might not even work in this case.

Apr 15, 2016
zerokewl I know Tesla wants to get rid of the mirrors to make the car more aerodynamic. so i think the HUD in the Need For Speed mustang (the movie) would have been cool to create�
Apr 15, 2016
shrspeedblade I was kind of daydreaming along these same lines. For the people who are driving and don't want lots of stuff to look through, maybe just speed and battery status displayed. When you enable Autopilot, it projects in front of you a far more advanced version of what the car's sensors are "seeing" of which what is currently shown on the Model S is only a precursor. This wouldn't only be incrediby cool and like something from a sci fi movie, but it would also make AP safer as you could actually anticipate more when it might be missing or misinterpreting something. I imagine toggling autopilot and a HUD pops up in front of me as the car "takes over". In the long term, I think it would make it easier to "trust" autonomous cars more as you're kind of seeing what they see.
Wouldn't it be great if Tesla isn't just dragging the rest of the auto industry into the 21st century with their battery technology and capability, but the whole driver interface as well? I know, it's a lot to hope for in a car with a $35k base, but if you're going to dream big anyway..............and if were the case, 325k reservations might seem modest down the road.
(This is my speculation, MINE I tell you! Bwahaha! And I don't want to be reading it later in a magazine or blog.)�
Apr 15, 2016
Topher Displayed how? I am expecting a remaining range display, how do you see that being most effectively used? The obvious way, is of course, warming colors as it gets critically low, but what else might be done?
Thank you kindly.�
Apr 15, 2016
tdelta1000 Great but will this updated tech for the Model 3 upset Model S & X owners?�
Apr 15, 2016
yesup Actually, the fact that the refreshed or face lifted Model S does not have HUD lowers the chance that Model 3 would have one at all.
It's just something Tesla does not think that it's necessary.
Coming back to the title of this thread, I really don't see any "proof" that there will be HUD.�
Apr 15, 2016
TslaIsFuture I think this current Model S refresh is 1 of many prior to the model 3 going into production. This is a car company that doesn't wait every year or 2 or 3 to make their cars better. It is done many times/year and in big ways. Expect many new announcements for the Model S and X before the end of 2017.�
Apr 15, 2016
Jason Bourne At least for right now, I believe Federal laws require at least one external side view mirror. So they may have to do some lobbying and waiting to be able to delete side mirrors.�

Noob1 Not a hud fan but keeping an open mind, keep it simple. It is still just a car.�
Apr 15, 2016
jamesp My BMW 335i has a HUD and I drive with prescription polarized sunglasses without an issue. Only compensating factor is I have the brightness turned up fully on the HUD.
I really hope there's a HUD on the Model 3 that will replace my 335i, however my "family car" is a Mazda CX-5 with a nearly unreadable and wildly inaccurate speedo, hence I typically use the GPS speed on the centre entertainment display anyway. It's not as good as a HUD but it's still workable.�
Apr 15, 2016
Litzy It could be that the HUD simply isn't ready yet and that's why they're hiring people with experience in that field. They have a little while to get it all sorted.
That said, I'm not sure that I believe it will have a HUD. I think it will have other types of feedback to help assist the driver instead.�
Apr 15, 2016
roblab So, you're saying you simply must have HUD so your eyes don't have to travel another few inches to the dash to check your speed? And you simply must have TACC or it's a deal breaker?
When I got Tesla, I sold my Priuses. Vastly better. (I am wondering where else your eyes travel that so wear you out that you must have HUD. Human eyes are very good at looking around, and I am positive that your eyes are not glued to the road ahead for hours)
Deal breaker? Please, feel free. There are thousands in line behind you.�
Apr 15, 2016
Beavis In my case, not at all. I've driven my S for more than 3 years. It's been a blast. I would rather drive the Classic S for 40,000 miles than wait for more tech. Why wait for the D, Ludicrous, Auto Pilot, X, Summon or the 3 (I do have a 3 reservation)? People like me jumped in with both feet, knowing that tech marches on.�

TaoJones Only 1-2 mentions of the side mirrors. Heh. They had side mirror stalks/pods on a prototype Model X since 2014. Once the regulatory powers that be get out of the way, I'd look for SHUD (side heads-up display, or a projection of what's behind/beside you right about where it would be (on the side window) relative to where the side mirrors are seen now).
As far as keeping Model S/X owners "happy", this doesn't have to be hard. For ease, roll out the technology across the production lines at the same time. Bundle it into the S/X price, and charge for it in the Model 3 variants.
Optional S/HUD seems like a winning option. If it's standard in all Model 3 configurations (and thus of course for all S/X), then I believe what we'd have there is a nice big fat DISRUPTION in the automotive industry
I would love to see it. The Model S is already the best seller, by far, in the large luxury sedan segment. Being the best seller in the much more crowded BMW 3 series/Audi A4/Mercedes C-class segment is a tad more difficult, but all of what we've heard so far does bode well.�
Apr 15, 2016
ikjadoon Err, that's because the Model S has an instrument panel... It would just be redundant to put a HUD there, I think.
And, if they just made this hire, the HUD cannot be ready for production.
If they want to re-do the entire interior of the Model S, maybe we'll see it in the Model S in 2018.
But, also: they don't have major issues with older cars not being able to get everything retrofitted, from what I've read. Some things yes, some things no.�
Apr 15, 2016
TEG My older eyes don't have the range of focus they did in my younger days. They are sort of "locked in" at about 2-4 feet for optimal focus. So, I am starting to wear reading glasses if I have to look at something very close, and I started to wear distance glasses for driving. The driving glasses work great for things out on the road, but then things in the cabin are a bit out of focus. It would be nice if there was a HUD that had a "distant focal distance" so it would show IP things in focus even through my distance driving glasses.�
Apr 15, 2016
yesup HUD can be designed to display the virtual image at any distance (as close as your windshield, and as far as infinity).
For example, my BMW HUD's image appears to be right in front of the car beyond the hood.�
Apr 15, 2016
AUSinator Exactly your spot on!�
Apr 15, 2016
BluestarE3 When I stopped being able to see my dashboard instruments clearly using my single focal length eyeglasses (for distance), I switched to progressive lenses. I have them for both my regular and sunglasses and they work great.�
Apr 15, 2016
omgwtfbyobbq The HUD on the Prius is great. Having speed, power, and driving directions smack dab in front of my face is awesome. The only issue I've found is that it's hard to see if the sun's at the right angle, but then again, so is the road.
My favorite thing about it the HUD being able to completely turn off the instrument cluster/touchscreen at night. Really handy in the country if there's no moonlight.�
Apr 15, 2016
S'toon What I want to see in a HUD is for the GPS navigation to point directly to the road I'm supposed to turn off onto so I can distinguish it from the road right beside it at a slightly different angle.
It was a bit of a kick in the teeth when I was prescribed progressives. "I'm getting old."�
Apr 15, 2016
omgwtfbyobbq Toyota's Nav/HUD already adjusts the angle/location of the turn arrow/roads based on the actual lane change/turn. I'm guessing Tesla can do as well if not better.�
Apr 16, 2016
BluestarE3 They're nowhere as bad as the old-fashioned bifocals with the split lenses... at least with the progressives, no one will notice you are wearing geezer glasses!�
Apr 16, 2016
UKM3 imagine the Pioneer Navgate HUD on an entire windscreen. That would be cool. Everything always in focus..�
Apr 16, 2016
malcolm I confess, I'm still struggling to get enthused about this.
It seems to be just taking the digital display which normally is embedded into front edge of a dashboard and remounting into the top of the dashboard.
Unless the display screen is made physically larger, it will now appear smaller/more distant when reflected in the windshield than when it was sitting in front of you. (Using a larger display to compensate would be more expensive - but are we considering that as an option? - see below).
The depth of the top of the dashboard limits the position of the display and hence how far it can appear up the inside face of the windshield (you can use a light on your phone or any torch and move it around to see where its reflection appears)
With the display sitting in direct sunlight and needing to be run brighter to offset ambient light levels and reflection losses from the windshield will there be lifespan issues?
/ debbie downer moment
Okay - bouncing back - here's an idea.
The reason why the tablet in the launch model 3 was mounted on a support rather than being embedded as it is the S, is because the HUD replaces it as well. The HUD runs the entire width of the dash so that the front passenger can use it too. Controls are provided on a second screen which is mounted lower down, between the two front seats (where you might be able to spill your coffee over it
Too expensive? Probably. Harder to control than a conventional touchscreen? More than likely.
Oh well...�
Apr 16, 2016
ecarfan The Tesla test drivers at the Model 3 reveal, who were high up in Tesla management, repeatedly stated that the center mounted 15" display would be in the production Model 3. They were very clear about that.
IF there is a HUD the center display will still be present.�
Apr 16, 2016
yesup HUDs are not a simple reflection of a display screen on the windshield (some of the 3rd party "HUD" device, or those HUD apps on your smart phones are, but they are not real HUDs). Properly implemented HUDs use optics - so it can "project" the display image to a larger size than the display screen, and make the virtual display image appearing at any distance (from as close as your windshield to as far away as infinity).�
Apr 16, 2016
arjay I'm loving this HUD possibility more and more! That Prius video is impressive.�
Apr 16, 2016
Nixx I don't think Elon will want to give away his secrets by putting them into the Model S first. I don't think he has learned from his MX "hubris". It's just way more amazing if one keeps everything under wraps until the reveal. I mean, maybe some Model S will have this technology after the Part 2 Reveal when everyone knows the deal, but that'll be only 60-90 days before the Model 3 starts to be manufactured.�
Apr 16, 2016
malcolm Thanks for clarifying that.
That's encouraging. Thanks.�
Apr 17, 2016
F_T_K I imagine a HUD with two cameras that track the driver's head position, so that the HUD display constantly adjusts to match the view through the windshield. Lane markers, signage, other vehicles, etc. I can also imagine a forward looking infra-red camera that feeds into those displays.�

Apr 17, 2016
phantom701 I actually much prefer BMW HUD over Prius. There's color and info do not go missing like what's shown in the Prius' videos.
I do like the Laser HUD idea because with my polarized glasses, the HUD display is washed out.

Apr 18, 2016
malcolm Ah okay. Now I get it.�
Apr 18, 2016
McRat I just drove around with the HUD on for awhile to figure out exactly why they suck.
The problem with HUDs in the real world is that they cannot detect what background color exists. They would have to have an eye level video camera sync'd to your exact POV. What some HUDs do to minimize this defect is to crank up the intensity, which is not a good solution since it makes objects invisible where the HUD image exists.
Instrument panels can control background contrast, HUDs cannot.
While the problem is worse at night, it still occurs during daylight hours. When a HUD works OK, it works. But you do not get to pick when it doesn't work. Driving into the sun aggravates it even more.
And what many people do not understand is how the human eye works. They believe your eye sees everything in front of you at once. No, your eye is constructed with a high resolution field only in the very center of your line of sight.
Here's an experiment for you that you can do at your desk:
Stare at some text you can read that is 2 feet away. Now move your focus down just 1", that's all. Do not move your eye, just read the text again. Notice that you can't? Your eye does magic trick to overcome this. It is constantly moving to fill in the low resolution areas in front of you. This happens in millisecs. It takes no longer to glance at the instrument cluster than the HUD text.
Yeah, HUD does sound like it's an improvement over instruments, but reality screws up the theory.�
Apr 18, 2016
evp Physics says that's not going to happen. The reflection off the glass polarizes the light in the exact direction polarized sunglasses are designed to suppress.�
Apr 18, 2016
Topher Could you explain this please. What determines the polarization of the light from the HUD?
Thank you kindly.�
Apr 18, 2016
voip-ninja The HUD on my last 3 series was awesome (for a number of reasons I didn't get it on my current car but at times I do miss it). It had multiple colors and showed a lot of helpful information in addition to speed. You could see radio/XM stations, media player tracks, navigation turns, it could even use the information from the cameras in the rear-view mirror to display the last detected speed limit sign.
Yes, I was miffed for about a week when I first got the car and found out that my Maui Jims wouldn't work due to them being polarized.
Then I realized that whining that a $200 pair of sunglasses didn't work with the HUD of a $50,000 car when the displays in $200M aircraft have similar problems was just stupid, and I bought a new pair of sunglasses... problem solved.
Polarization filters work in one of two directions, either vertical or horizontal. If the display you are looking at is built vertically vs horizontally the polarized glasses might still work... kind of.
It's really not worth worrying about. If the Tesla has a HUD then get over it and buy some new sunglasses.
Because physics.�

Xminus6 I would assume the camera's frame rate and the HUD's refresh rate are out of synch. Pretty common in video for even things like overhead lights. You can even see this in the Model S's rear-facing cameras with certain cars' driving lights. I had a Mercedes behind me yesterday at a stoplight and the driving lights (eyebrows) were phasing all over the place in the rear view.�

ModelNforNerd
Why can't it be both?�
Apr 18, 2016
zenmaster I hope you don't teach physics. Short answer to the assertion is no. You typically have either horizontal or vertical polarization of light - be it reflected or filtered. It's when there is a match that you get the cancellation.�
Apr 18, 2016
GBleck Think of light as a bunch of particles wiggling like the surface of a wavy body of water. The difference being that each particle is waving in a different direction. Some up and down, side to side or in between. When they strike the surface of a transparent surface like water or glass only the ones going one direction get bounced off the surface and the others penetrate. Polarized glasses filter out he light that is polarized from reflections off horizontal surfaces like the surface of the water around your boat. The problem with hud reflections is the wind shield reflects the image to you the same way light reflects off the ocean. Polarized sunglasses filter out that image like a reflection. If you bounce the image off a surface that is tilted 90 degrees from the normal direction of a wind shield that might work but at that point you really are building a jet fighter HUD. Also most display systems use polarized filters to control light passing through them. Two polarizing filters at 90 deg will stop light but at the same angle let it through. If you can't see the display just tilt your head and it should pop back up dim but viewable. Optical physics is trippy stuff, no?�
Apr 18, 2016
GBleck Thinking about it some more you might be able to get an in polarized light on the inner surface of the windshield if you coated it with an oriented organic molecule film that emits light in either the correct polarization or not polarized. A laser HUD perhaps? An cathode ray tube would be epic but I'm not sure if it would work, or make the driver glow in the dark like something in fallout 4. Atomic age punk as hell though.�
Apr 18, 2016
ikjadoon Tesla is good about accommodating customers, but not always. Sometimes they have a vision and they expect consumers to adapt.
Like, the cupholder situation (thankfully remedied) and the door pockets. And the non-adjustable seatbelts (fixed on the Model X). And the massive touchscreen instead of knobs and buttons. Most people have to adjust to these things.
I think most automakers have moved towards HUDs especially in the luxury market, even with their loss of function with polarized glasses.
Someone mentioned that you can partially rotate the HUD, so that it is neither exactly vertical nor exactly horizontal. Apparently, it's less bright, but at least it is visible. Any physics experts want to chime in?�

WichitaHack I do not think it with have a HUD either.....at least I am hoping it does not. I would still love a traditional digital instrument cluster. What ever they decide to do, I am sure I will love it though. I trust Elon.�

zenmaster You can either rotate the display or rotate your head. On my system, HUD brightness ranges from 5% to 80% through polarized lenses, depending on head tilt angle.�

Garlan Garner How does a HUD look on a frozen/fogged-up window?�
Apr 18, 2016
McRat It's image is projected on the glass at a distant focal point, so when the windshield is covered, it's a trip. It appears further way than the ice, kind of like a 3D movie effect.�
Apr 18, 2016
yesup I think if you cannot see through the windshield, the HUD display is the least of your worries
Anyways, HUD is a reflection, it's like the mirror in your bathroom, in the situation where you can't see yourself in mirror (fog, ice.....) , you won't be able to see the HUD image either.�
Apr 18, 2016
Garlan Garner Wow, I would have to experience that.�
Apr 18, 2016
zenmaster If you can't see through the windshield due to interior fogging or ice, I don't think it will be reflective. The HUD projection requires a reflective surface to hit your eyes.�
Apr 18, 2016
evp Light gets polarized when it reflects off a surface. Look at the illustration here: Brewster's angle - Wikipedia, the free encyclopedia
Polaroid sunglasses suppress sunlight that has been polarized in the horizontal direction by reflection off surfaces that are oriented horizontally, like water, roads, etc. The reflection of an image off the windshield is also horizontally polarized, thus polaroid sunglasses are effective at suppressing reflections of things sitting on the dashboard. This includes images projected from the dash into the windshield. Try the experiment: put a piece of white paper on the dash, observe the reflection without sunglasses, then with them on. Let us know how much the reflection is suppressed.�

Xminus6 That surface is in the inside of the window. In the BMW there's a small patch of material on the inside of windshield that reflects the HUD. So you should be able to see the HUD even when you can't see out the window.�
Apr 18, 2016
zenmaster Presumably, if that patch is covered you can't see the reflection. A sheet of interior ice should work great for covering the patch.�

favo From TI's web page on their DLP HUD:
The vagueness of the claim does allow for the possibility that polarized sunglasses do compromise the experience in some way.�

Model S M.D. Didn't have time to read through all of the posts, so sorry if this has been posted already. Would be cool if the HUD/Autopilot looked like this:
BMW just showed off its new concept car � and it�s 100 years ahead of schedule�

stopcrazypp In your experiment however, the paper may have components that are horizontally polarized, but also those that are not horizontally polarized. So yes, if you wear sunglasses the reflection would be notably suppressed (because the horizontal components are suppressed). However, that doesn't necessarily mean all components will be suppressed.
If you have a display that is vertically polarized, then none of the light would be blocked by the polarization of the sunglasses. If it is 45 degree polarized (as is more common), it'll be dimmed. If horizontally polarized it'll be invisible.
Reading forums, it seems BMW HUDs are completely invisible with sunglasses, but GM HUDs (even the old ones) are still visible with sunglasses (although possibly dimmed). The latest color one (which may be using the DLP technology discussed above) seems to be best (clearly visible even with sunglasses).�

CyberKnife Seems like everyone is quite sure that a HUD will be offered on the Model 3. I wouldn't mind it but I would not set up hopes or desires on it in the case that a dash screen like a Prius is offered instead and feel sad about it.![[?IMG]](https://lh3.googleusercontent.com/blogger_img_proxy/AEn0k_uYVgKTE5g6qVxcpAABIW5yjfO94j48SRyvcyI9gWjTE4x4IhgpxGWXAYeYxqfbIS5rz-fmQUlxaRUiqNG25ryIJIzra5Wv_m9fYAVSeQR0UNdnorcU5l6BTgyO-To37HZz=s0-d)

Xminus6 I've never lived in a location where ice developed on the inside of my windshield. I've had some fog and condensation but ice? I'll defer to people who live in climates that cold.�

opbayarea I am more inclined to think that the steering wheel will have an LCD screen as a replacement for the instrument panel. This design is probably the easiest choice to bring unique innovation into the mass market car (tesla will be the first) and keeping in mind that the car needs to be manufactured for right hand/left hand with common components and minimal reconfigurations. Formula 1 cars have long utilized this steering wheel concept. An Inside Look at the Insanely Complex Formula 1 Steering Wheel�

Topher No thanks. An easier choice would just be a regular instrument panel. Better choice too, IMHO. I want to move the information FURTHER from me rather than closer. I certainly don't want it spinning around and being blocked by my arms.
Thank you kindly.�

zenmaster You quoted my post which referred only to the insides of windshields?�

Hank101 A data phone (or Bluetooth monitor) with an OBDII Bluetooth dongle, and the right app, can be used as LCD dash - place it where you want it. Volt/Prius/Leaf owners do this often to track battery range and usage.
Also, HUD, or data could be projected onto the white dash behind the steering wheel, simulating an LCD dash, which may be a lower cost option. This (projection) may also allow greater user customization, including on/off.�
Apr 19, 2016
zenmaster Wouldn't work with current dash due to being too low and obscured by wheel.�
Apr 19, 2016
NickHoffmann I still have my money on a transparent LED film embedded into the windshield. No projection/reflection HUDs.

sebxx using projection would make it challenging to read during sunny days
or maybe the white part will be an entirely OLED panel (customize theme or info you'd like to have, same for passenger)�

ModelNforNerd except the whole "ease of manufacturing" mantra they're trying to stick to with the Model 3.
I would imagine that windshield would NOT be cheap.
Plus, in the Northeast, the 1st time you chip it, you're done.....Safelite can't fix that.�

favo They have played with projecting images onto glass at SpaceX for design and manipulation with gestures.
Go to about 2:18 to see the glass projection. There's your spaceship-like interface. Clearly, the steering wheel will be removed, and you'll drive the car with gestures.�

Big-T You've got 4 cars all with HUD's already? Are you some sort of futuristic car dealer?

Garlan Garner Again I hate HUD.
I would vote for this steering Wheel with the screen.
A steering wheel that will fold away.
