180,000 rides a week happen right now using this practice for Waymo right? They are just copying the practice. 0 cars are being driven by remotely people to and from places. It's fear mongering. If a car gets stuck because it's sensors believe something is in front of it, it will stay stopped and flag a handler to evaluate. The person will say your fine move forward or tell the vehicle to stay where it is until someone moves the shopping cart someone left behind it. Once moved, they'll re-enable the car and it will go on its way.

If there is actually something wrong like someone rear ending it at a stop light, then they may put it into some liml mode, give it a parking lot close by to pull into while they watch, then turn it off to await someone to show up and assess damages.
