In the case of avoiding parking by having your car circle, surely you see that having several hundred or more all doing this would make our roads impassable congested.
This is why in san Francisco for example we are limited to a grand total of 2000 taxis. All cities limit the number of cars in this service for this reason (NOT to simple create a costly monopoly as is so often claimed)
Uber came in and our congestion has literally doubled. They are not limited and people use them instead of the bus and/or instead of driving no and parking.
Then provide free parking....
