I expect you're going to see automation go a lot further in enhancing people's driving than you'll ever see robo-taxis be a viable primary mode of transporation. So it's probably not necessary to worry about human drivers being illegal, but you might see cars without key safety features become illegal the same way seatbelts and airbags are required today. So no more riding the shoulder, automated enforcement of traffic laws (so no speeding, no rolling stops, must yield at a yield sign, etc.).
