well, he's still free to do that too
it is illegal to drive with a car that does not have license plates on it. i believe it is also illegal to drive without functional lights on the car, not the mention very dangerous. i don't know where you got this idea.
you really can do whatever you want with your car. limits like that aren't telling you what you can't do to your car, exactly. they're just telling you what you can't do on their roads, if you do certain stuff to your car
again, from what i can tell the car was leased to deadmau5, so it wasn't actually
his, he just was allowed to drive it. really there's no point arguing about him being able to do anything to his car -- we all know that, we're not stupid, but for one it isn't actually his as i've stated before, and two even if you
can do whatever to your car, you have to have it within a specific set of guidelines for it to pass inspection and be allowed to be driven on the roads.
