I could care less what other people do to their vehicles, I did plenty of stupid s h !t too but grew up and tired of much of it. The only part I disagree with is the fk'tard vandalizing the guys car. I can't stand muzzle brakes, especially on AR15's at the range with people who are plinking at the bench. As much as I hate that s h !t I have no right to walk over and dump a handful of sand in the open action.
The Corsa Extreme is one of the biggest offenders and I can't stand them because they are seriously loud under power.
