Just another unintended consequence of road use being free for its users, despite road space being a limited resource that's expensive to build and maintain. Congestion pricing is already a (crude, but still rather effective) way of solving that problem. A more perfect (though impractical to enforce) solution would be charging by the meter-second of lane space consumed, with rates varying over time and location depending on congestion. Under that pricing scheme, if driving in circles were still somehow cheaper than parking then cars could drive in circles to their heart's content without causing any issues.
