Speaking of Audis, that reminded me of something I witnessed a few years back. I was sitting at a red light at an intersection with a notoriously long delay. In the lane next to me was an Audi coupe of some sort or another(don't recall the model). There were no cars behind either of us.
The Audi presumably had a manual transmission, and the driver would periodically pop the clutch, roll back a few hundred feet, then rev the engine like mad to pull up to the line at the light. I watched him do this 3 or 4 times.
I also saw a police office coming up the road, and he pulled into the lane behind Mr. Audi. I don't think he realized the cop was there, as he pulled the "roll back" stunt again only to find his rearward progress impeded by the push bar on the front of the Police Interceptor
. Needless to say, the officer lit him up, at which point the light changed and I pulled away laughing.
I would have loved to have heard that conversation during that traffic stop.
