Maybe its just me, but I hate when people who drive the $hittiest cars ever pull up next to me or my friends at a light and rev their engines.
Example:
I was riding w/ my friend in his '03 Accord EX V6 6-speed manual (240HP). First off, we're in the left turn-only lane. In the lane to the right of us, an extremely dirty-looking guy pulls up next to us in an old Corsica, stares over at us, and revs his engine. Now, in case you don't know much about the Corsica, my old roommate in college had one. It was a POS. But... my roommate's Corsica was in much better shape than this guy's. Needless to say, we could have smoked him off the line... but even as I motioned that we were obviously turning left and he was going straight, he continued to stare, nod & rev his engine.
