New Augmented Reality HUD Is a Fighter Jet Display for Your Car

Just yesterday, there was a 130 vehicle crash here in the UK (sadly, that number was not a typo) after thick, low fog moved in over a bridge that is normally a major high-speed route. If everyone's vehicle had been fitted with technology that detected reduced traction due to the greasy road surface, how close vehicles in front really were and how abruptly they were slowing down even if fog was obscuring them, and how fast each driver's own vehicle was really going, and if a HUD had then flashed up the essential information and highlighted the insufficient stopping distances drivers were leaving, there might have been many fewer injuries, much less damage, and much less disruption treating the injured and recovering disabled vehicles. While yesterday's weather conditions were unusually severe for the UK, similar arguments would apply all the time at night for anyone driving on high speed or bendy out-of-town roads.
On the other hand, was I the only person who watched that video and got completely distracted by the zooming route map towards the end? If I were driving for real, I think it would be very difficult to concentrate properly on the road ahead with all of that activity going on. Avoiding information overload and maintaining driver concentration seem like serious concerns for this kind of system, but as a UI guy it looks like an awesome project to work on.
As the Sheppey pile-up demonstrates, there's a lot of people who simply suck at driving - specifically maintaining sufficient braking distance and NOT cutting into someone else's braking distance when changing lanes (in poor conditions that space is for ME to stop in, not for YOU to slide into). As it is, I'm conscious that I need to be aware of the car behind as well as the car in front. The only way it'll work is if the car brakes for you, and then everyone has to have that technology.
For my driving I like to be able to see clearly through the windscreen at all the things that are going on around me. For that reason I keep the windscreen clean and I don't like having any windscreen mounted things (like a cellphone or GPS).
I'm much happier in one of two modes: looking through the glass at things around me (road, cars, people, bikes, etc.) and looking at an instrument for data (speedometer, GPS, fuel, etc.)
I can glance at my GPS and know what's going on when I need to. Similarly, if I need a quick speed check. I really don't want these things in my field of vision when looking through the window. I think a HUD with any sort of motion of changing data would be incredibly distracting.
There's a company already doing this, the Pioneer HUD is kind of a rip of their concept:
TTS is getting good enough that I think GPS units without displays at all may be perfectly serviceable. As it is, I almost entirely go by sound with mine already.
There are some pretty tricky optics involved in getting a light path of the right focal length in the room just under the windshield and the first part of the bonnet so the image appears at the right distance.
I think a HUD may become standard in most cars within a few years because its just much safer to have information or controls projected in your field of view than to have to look down or away from the road. And so many people have long commutes with emails or instant messages coming in that they would like to be able to monitor without taking their eyes off of the road. Even if you are changing your focus or attention slightly, the time to refocus on objects that are still in your field of vision or only a few degrees away is much less than what might be required to switch away from viewing a phone in your hand.
Then perhaps they should consider taking public transportation? These kinds of HUD technologies could do a lot to make important driving information more easily accessible, but given the overwhelming evidence that trying to concentrate on remote communication while driving dramatically increases the risk of and damage caused by having an accident, it's hard to believe that shoving all that information between the driver's eyes and the road could ever make that kind of activity acceptably safe.
And that reason is: most people, for most trips, just don't need it. [1]
Driving a passenger car is simple and boring. That's why people distract themselves. That's why they go on mental auto-pilot and will readily admit they weren't consciously aware of how they got from one place to another.
Even if and when that data is front and center, it gets tuned out with everything else.
[1] Turn by turn is great, but it's explicitly for the minority of cases. (business travelers, outliers, notwithstanding)
What? That's crazy. Mini projectors can be bought for about $200, and this could easily run a slow display over bluetooth or literally anything over wifi (then it's just a video stream to a mini projector with a special lens and a piece of glass).
Good idea, bad idea, I wouldn't even consider this with that kind of price tag.
