Seems to me the average car has enough distraction without more @#&* thrown in. Just driving can be rather distracting as people make left turns with the right signal or none at all on, across lanes of traffic.
Like a speedometer?
I have a good idea my speed and what the speed limit is.
I wish I had a dime for every time somebody said "I
don't think I was speeding <haughty sniff>".
So many people either have
no idea of the legal speed limits or they're actual speed or they just don't care until their caught.
And gimme another dime for every time someone has said "I thought we're allowed 10mph over."
I would not want to use one in a vehicle because of that complexity.
WTF?
Surely you're not equating an aircraft or other milspec HUD with what should or shouldn't be in a vehicle.
I've not driven a car with an HUD, but I've played with adding a cheapie to my bike.
Out of the box it had a bunch of needless red wheels that I covered up with black tape.
I found I paid even more attention than usual to my speed.
So many displays focus on having a golly gee whiz bang display, and that usually means including superfluous to useless information on the windshield, along with redundant iconography.
A simple HUD of speed is really all that should be up there, along with any warning indication such as low level fuel, low or lost of oil pressure, battery warning, TPMS warning, etc.
Wind velocity, direction, true air speed, nearest In-n-Out, etc., don't need to be there.
Aside from one's speed, and the occasional warnings mentioned, if I were the demigod of the US, I'd mandate a HUD for very vehicle sold, with very few exceptions.
It would have the vehicle speed in numbers, along with the speed limit in smaller numbers, underneath.
Ok, maybe experts would have to sort out the specifics of those two for immediate cognitive recognition.
Let people have the option to turn it off, if they're easily distracted by those two pieces of information.

Your boos mean nothing to me, I've seen what you cheer for.
Insisting on your rights without acknowledging your responsibilities isn’t freedom, it’s adolescence.

You and I have memories longer than the road that stretches out ahead.
