>So.. there's a driver in driverless cars. A fall guy that will take all the blame should the company needs to produce someone to be arrested

Are you seriously pretending the driver doesn't have agency here? This accident was easily preventable by the safety driver, which makes the "fall guy" characterization misleading. Sure, maybe there was some risk of complacency, but what's the alternative? Should uber have gone full workplace surveillance and have a camera trained on the safety driver's face, to make sure she was paying attention?
