A car which tells you when you're about to reverse into the path of another car is safer. I don't really know what to tell you. It's obviously safer.

Sure, but that's a different kind of safety than _crash_ safety.

Plenty of people (rightly or wrongly) are confident in their ability to prevent accidents. Or, at least, confident enough to be skeptical of the tradeoffs involved with these assistive systems.

If I had to choose between a car that has high survivability in a crash versus a car that how worse survivability in a crash but has a few assistive systems that can prevent some crashes (which, mostly, I already prevent by paying attention), I'd choose the former every time.
