If you go to an auto show or a dealer, these are the type of cars that are sitting behind velvet barrier ropes, with a man in a suit giving you the stink-eye if you linger too long. Vegas Supercars leaves them all in their lot with the doors unlocked. Even if you're just doing the ride along and haven't paid to race them, you can walk up, open the doors (even the gullwings) and sit down. They encouraged us to poke around the cars while we waited for our turn, which really enhanced the experience.
