I could see projecting information that's useful to other drivers and pedestrians. A rectangle indicating your stopping distance would be useful for cars intending to merge in. A turn signal that is projected forward would tell people entering a cross-walk "there is a car trying to turn across this, watch out for them and make eye-contact". A rear-projection rectangle would indicate a car is in reverse and may back up without seeing you. The problem with all of these, and any other information is that they really only work at night, so...

I partially agree. I think this system is useful, but only for very simple spatial data. Having the car project a line one car length ahead and flashing bars synced with the indicators would be a major improvement over a standard unagumented view; however once you start trying to be fancy with symbols, letters, and numbers I feel any improvement in spatial awareness would be canceled out by the extra cognitive power needed to parse those symbols combined with the extreme clutter created by every other car on the road doing the same thing

Perhaps it should project a yield to pedestrians symbol warning the driver that there is a pedestrian in the crosswalk

Could just broadcast that info to cars around, ADS-B-style, then put it on HUD. Probably pretty hard to make it secure tho I'd love to see info "the car in front of me will be taking right soon, or exact speed just displayed via HUD on top of the car.

I was initially very much against the idea, but this comment kinda put me in a 'maybe not a bad idea' camp. Naturally, the stuff will soon be hacked to project all sorts of other things, but that is, for better or worse, standard human behavior.

Nah, the real problem in my experience is people don't care. It's rare for people to even give me half of the distance they should when they merge. The full distance? That would be a miracle. It's hard for me to give the full distance. People just start passing me on my right even when I have my signal on.
