Perhaps we have a dilema. People have shown, time and time again, that even though most consider themselves good drivers, they still get into thousands of accidents every day. The human mind, just does not tend to remain totally focused, every minute they are driving. Even then, our two eyes, two hands, two feet and one brain, are not always able to instantly process the actions necessary to avoid every possibility of an impact.
Every day, people are killed, maimed, and vehicles damaged by well meaning human drivers.
Tesla is attempting to develop an AI/computer, camera, vehicle system to take some of this load off.
People are resistant to change and feel pretty self important.
