For all you nay sayers realize you more than likely have ridden aboard an airplane that self landed that otherwise could not have landed at that airport due to low visibility. I my 34 yrs of airline flying I never had not once an autoland fail.
I'll put my faith and life into a robot before I risk driving next to a distracted/incapacitated/mad/suicidal driver. I'm 67 and do believe that totally autonomous cars will be available in my life time. The general public will demand and pay for it and car manufactures will meet that demand.
I can't wait for my motorhome to be self driving. We'll start from home after dinner, watch some TV, go to sleep and wake up the next morning in a campground next to the Grand Canyon. It's coming weather you like it or not, just wish I was 10 years younger.
