Driverless cars have the unique ability to move without requiring an operator to be present. They could be allowed to park in regular spots, loading zones, tow-away spots, etc., for "free" if they provided a mechanism that enables anyone to tell it to screw off and find another place. A button on the side of the car for pedestrians and an rf receiver for people in vehicles. I think there should probably be a tax leveraged against the owners for the increase in congestion and the reduction of the number of spots available to people without the device that tells driverless cars to scamper away, but I don't see the apocalyptic 'circling-the-block' scenario happening here. It would be cheaper for the owner to put the car into this non-imposing parking mode than the circling mode, so they would choose the former.
