Actually, autonomous car operation is more likely to be found in congested cities where safety is less of a concern because travel speeds are low. I think Pittsburgh just rolled out a pilot program with fully autonomous taxi cabs in the center of the city.
Just center city or up into the surrounding hills? I’ve often thought those hills would be a very scary prospect in an ice or snow storm. Steep, San Francisco level steep.
Cabs/Uber and long-haul trucks will be first.
Those “fully autonomous taxi cabs” in Pittsburg have drivers.
Don’t be fooled by hype or poor reporting. The difference between a 99% autonomous car and ‘fully’ autonomous car is huge.
