I do the same thing... I'll rev on a faster car and take off just to see it run/how much it will beat me by.
Same thing happens to me too... just yesterday I had 4 guys in a brand new dodge truck(the one with 20's) pull up next to me and start goosing it and motioining me to go. I just shook my head and they kept up so finally I dropped it down to 2nd and left them far behind.
