lol..i was just talkin about this the other day...its a pet-peeve of mine. Its not so much a thumbs up or a wave ..its more the ones who feel it neccessary to slow down next to you or make you roll down your window just to tell you "cool car" or " i use to have one just like that when i was younger" or "hey what year is that" i cant escape goin for a 10min drive to the corner store without answering one of them. So myself i could live with dorky thumbs up just as long as i dont have to turn down my tunes roll down my window and answer the same question over and over
