I have been a biker for many years. I have been a Jeep guy for many years. There are forums for Jeeps and bikers. Of course, there are forums for Corvettes and just about any other vehicle you can imagine.
One of the big topics of discussion on these boards is "The Wave". On the Harley forum, you regularly get a thread that starts with something like "I wave at every other biker I see, but I noticed a lot of BMW riders don't wave back. That really bothers me. Do they think they're too good for everyone?" ... or in the Jeep forums, someone laments how driving a non-lifted Grand Cherokee, he is denied "The Wave" by many in lifted CJ's...
Why don't Crossfire people wave at each other when we pass in the street? If we did, we could have threads here about how someone in a base coupe felt slighted because someone in an SRT6 didn't wave back at them!
