You can assume that the taxi driver will be able to react to most possible events on your ride home. Right now self driving systems require active oversight and you can't sleep while you use them.
It's like comparing an experienced driver (taxi or not) and a student driver. I'd sleep with an experienced driver driving but I wouldn't even think about sleeping if I am being driven by a student driver.
