Doesn't this upend Uber's whole model of non-ownership of vehicles and rejection of liability? Unless the driver is just there to be liable for having "allowed"

Doesn't this upend Uber's whole model of non-ownership of vehicles and rejection of liability? Unless the driver is just there to be liable for having "allowed" the AI to intentionally hit something or someone! Also, as a NYC driver, I wonder how aggressively a self-driving car could legally be programmed to defend its lane. I'm picturing Uberbots sitting still in traffic while streams of human drivers gleefully cut them off. City driving is basically a game of chicken every 10 seconds; winning at chicken depends on convincing your opponent that you are willing to have an accident.
