Yes that's true, I can certainly imagine it as a possibility in the future. Specifically for motorcycles, as many experienced riders would say, sport bikes especially can hardly even be used on public roads anyways. My old bike red-lined 1st gear at ~96mph, i.e. there isn't a public road where it is legal to "use" the first of 6 gears. They're made for a track. On the other hand, RE: safety, in the overwhelming majority of cases the safety risk on a motorcycle is to the rider not the other drivers on the road. Motorcycle accidents where the rider was at fault and a vehicle occupant was killed are likely less probable than death via choking on a bagel. So a outlawing human drivers in this case sounds more like taking away an individual's choice rather than controlling any legitimate risk to public safety. As for cars, I agree that it will probably at some point make sense to separate autonomous cars from human drivers. There is not much way around the fact that you can kill other people easily in a car, and that a great number of people would justifiably want to opt-out of that risk if they had the option. Someone's enjoyment of driving won't be nearly enough to justify otherwise that when the time comes.
