I know how you feel. I used to see a white Z4M. I'd pull up next to him at the stop sign or light, look over and kind of wait for him to look over so i could wave hi, (while i'm in my Z4M mind you..) He looked at me once, like i was some insane person wanting to rob him.. So i was like **** him, rolled on. I don't get it sometimes. I get more waves from Harley's and Goldwing riders while on my BlackBird than i do waves from other bmw owners. NON-BMW owners wave all the time...
