I'm a total car nut, been reading car rags since age 8, and am a great driver. But I can't wait for these things to show up and take over.
Traffic is such a bear, everyone else drives distracted (or drunk) or sucks at the task. A computer is awake, responsive and always optimizing the trip.
Insurance rates will drop, travel will be quicker and less stressful.
And for real car nuts, there will be a surge of 'road tracks' that will cater to our need for control AND speed. I'm lucky to live 5 miles away from one such track, and it's incredible to be able to really push your car and yourself to the limits. Makes roads seem such a bore/chore with all the other idiots out there.
So, expect to see more automated driving happen over the next 20 to 50 years, as well as growth in private driving clubs for those that really care.
