I couldn’t own a car without it anymore.
I definitely don’t feel Tesla is responsible for the crashes caused by people ignoring all the warnings and notices. People have been ignoring warnings and dying in stupid ways since warnings first existed.
When I read the manual it specifically called out several situations where ACC could cause a problem. Completely stationary objects and using it around a sharp corner can cause it to lose sight of the car in front of you.
As you said people have found stupid ways of dying and not paying attention while driving is one of them. I keep an eye on ACC and will keep my foot above the break if my intuition tells me to.
