One funny thing about art cars is how quickly some people start acting like they own the damn thing. They're on it for 5 minutes and suddenly they're the spokesman for the car, telling new passengers how it was built, where it's going to go, whether they can get on, etc. Even the driver might just be some random campmate of the owner who doesn't quite understand the rules. As with most things on the playa, don't take it personally. You usually have no idea who you're actually talking to or what BS they've had to deal with that might have put them in a bad mood.
And please don't be shy about trying to get a ride just because you got blocked from one car. Please keep trying! Most of us bring the cars because we want to give people rides. I may be overloaded the first time you see me, but I'd love to meet you the next time we cross paths if there's room.
