For many years I had a ten mile commute to and from work.In the morning,75-80mph and 12-15 minutes for the commute.The five o'clock parking lot gave me much time to think about traffic.I concluded that if we all used self driving cars traffic could be much smoother and that I might get home in less than 40 minutes.
Ignoring the big brother aspects and just focusing on the practical,I think that they're a good idea.Also,a good friend of mine has two daughters,now 22 & 24 I think,that didn't even want to get licences until after high school.They didn't see the point in driving because they always rode the bus or got a ride.I believe that they'd embrace the idea immediately.
