i dont think there is any such "elitism" on the roads,
However people do treat you differently depending on the type of car and also your driving behaviour.
charge up behind someone in the outside lane in a big 4x4 and people tend to get out the way. do the same in a small car and they dont.
act aggressively on the road in a german car and generally people ignore you or give you a cunts response. do the same in a normal car and theres more chance they will get out your way.
