Regardless of whether it was an ‘art car’ (which are almost as a rule not “street legal”), or a ‘functional vehicle’… the point is still that they are driving on the Black Rock Desert.… not a public highway. If the car is not street legal, yes, it gets towed or flatbed trucked. But once inside the private event, that is taking place in a total wilderness area… standard street rules wouldn’t seem to apply. Same for dune buggies driving on dunes, stock cars driving in smash-em-up contests, or any other ‘non street legal’ vehicles that exist.
The point is not that they can contest the ticket, it’s that the ticket should not have been written at all… because they are on the playa. So the ticket comprises harrassment. Because some hater bureaucrat is all buttsore from losing a court case that didn’t involve the driver of the vehicle. Lame.
