If human drivers were supplanted by computer control, they could go through intersections at 150mph and miss other cars by only an inch. Surely scary if looking out the window, but thats how packet switched networks operate today. Vehicles could also be designed with interior comfort, entertainment, business, and safety in mind.
I trust a triple checked and verified computer system more than a texting teenager or a 75 year old man whose one speedbump away from a stroke or heart attack. We lose over 65k people per year in car wrecks, far mor than the 5k we've lost in nine years of war. People might not like dying because of a bug or glitch, but by the numbers, I think a properly designed and controlled system would, in total, result in less loss of life.
That being said I'd still want the option of some offroad rally action or a stunt course with some slick road action. I don't wanna take the passion out of driving, I just wanna increase the safety of the daily commute and make it less boring.
