Birds of a feather snub together. I even see it on the road with my fellow Corvette owners. Yeah, we have that "wave" and all (and it's kind of cool when you think about it). But, you're still finding yourself comparing your ride to the next guys. I think it's just simple human nature, no different than dogs sniffing each other's azz. If you get snubbed, just roll your eyes and continue to enjoy the ride.
