Seriously, friends. You suck at driving.
I have been driving for over 50 years. I have never hit anything accidentally. No tickets since the 70's and only two then. I have hit another vehicle intentionally but that is a different story... Crash bars are handy when somebody is about to run you off the road.
Auto cars should require at least one hand on the wheel every 30 seconds. An open eyes detector would be a good idea. Even then it will not work with many of the vehicles currently on the road. There is some pretty crazy shit on the roads, especially in back country roads. I wonder how they will fare with logging trucks? Every load they look different and are frequently covered in mud. The driver nails a ribbon on the longest end log at the back but that is not always visible in a short while. I have just barely missed being killed a few times. That was because I anticipated the possible mistakes like a shifting load.
Biting the hand that feeds IT
