Here in the south, everyone waves at everyone else... when I go back to jersey to visit, people look at me as though I have lost my mind when I start waving at strangers... :)

Too much work.....
 

I've never seen a BMW owner of any description wave at another around here. There's waaaaay too many Bimmers around and it would lead to countless rotator cuff injuries among the public and an unnecessary burden on the health care system.

While pulling out of my community this morning and merging onto the highway, of the six vehicles in front of me, four were BMW's (540i and three X5's). The other two were an M-Class Mercedes and a Porsche Cayenne. Pheeeeew.... imagine the sweat you could work up waving at everybody. ;)

lol... That's good stuff.
