Self driving cars? Whats the point?

I don't think so, not for many years anyway. It would take a while to get everyone "converted over" to a self driving car. What they need to do is test it in the form of public transportation for a few years. A self driving bus, or taxi service. See what it does in crowded city traffic before pushing onto the masses. The closest thing I have ever experienced was the self driving train at Atlanta airport, its pretty neat, but its on rails. I remember being freaked out for a second when you think that there is no one behind the wheel.
My new truck puts on the brakes by itself it it thinks you are coming up too fast to the car in front! flashes red LED on the windshield, seat vibrates and it slams on the brakes! I turned that OFF! So they are getting "us" use to the idea of "self driving"
