Smart, cars...buses...semis for people that have proved they can't drive ? "Maybe" not a bad idea...but for good drivers, I personally never trust a computer to do my driving.
Man, it;s nice to walk wherever you want and not be walked. It's nice to own and drive a car and not be driven. It's nice to have your own dog or phone and not borrow it, to have your own house and not rent it. It's even nice to shake hands with a taxi driver who will bring you what you tell him/her or ask in case it is not clear. To talk to the driver a bit . Self-driving cars - a useless idea.
useless idea? 1.3 million people die every year due to human drivers every year. I will see how you sing when one of your family members die due to a drunk driver.
