If we can replace all drivers by robots, what matters is whether the robot is better than the mean human. Of course, it’s not all at once. It’s about the marginal change. What matters is the mean taxi driver, who probably isn’t drunk. Another margin is the expansion of taxis: if robotaxis are cheaper than human taxis, the expansion of taxis may well be replacing drunk or tired drivers.
