Wonder how well they will do with flooded roads. Will they turn around and not drown. My significant other is a lyft driver, the other night she had a drunk rider and he became unresponsive. And fell on the flood of the van. She had to stop and check him. Get back back into his seat and at his destination go knock on the door for people to come get him. Would the driverless car do all that? How well are the on snow covered roads as well? Anyone road in one is heavy snow like conditions?
