So if you get into a crash, you would rather not have an extra few hundred milliseconds of deceleration? You would rather have more costly repairs, more injuries, maybe even more liability? I just don't see what you get in exchange for that by avoiding these features, or what principal is at stake

What crash?

My car already has this awesome safety feature called a "windscreen". It's a bit of thick glass about a metre and a half across, kind of like the screens that cars now have inside but here's the clever bit - it lets you look outside the car! It's completely transparent with no electronics (although mine has very fine wires embedded to heat it to clear ice off, that's not really "active" in any sense).

By looking out of this "windscreen" at other things in front of your car, you can prevent crashes.

Ah, I see where you are coming from. As a driver with perfect attention, zero ms response time, 360 degree vision and a car that never fails in a world where no other driver ever makes mistakes, this feature doesn't help you.

You still never articulated an upside to not having it though.
