If safer is a realistic outcome, perhaps things would further evolve. Ride share cars today are dual-use vehicles that typically carry driver + no passenger or driver + one passenger with the capacity for 3-5. If future autonomous ride share cars turn out to be dedicated to ride share, maybe most would end up being 3-wheel with just one or two seats. Shrinking the size of a substantial potion of cars on urban roads could be beneficial to road safety, power/carbon intensity, road capacity/density (which could also lead to more equitable road use for bikes and pedestrians).
