I'm gonna have to 'side' with exdeath here. Quotes because I'm not 'taking sides,' but this is internet, so that's what it's interpreted as.
I'm pretty sure he's the same type as me. If I'm driving a fast car, especially one that's 'flamboyant'- often meaning 'loud' in an uncontrollable 'the car would not be fast if it didn't have a fairly wide-open exhaust' kind of way, not a 'I'm going to rev my straight-piped hillbilly piece of shit as people' kind of way...
...people will do dumb shit. Like rev their straight-piped hillbilly piece of shit at you. And I'll do what I would bet exdeath does: get away from their dumbassery by showing them your ass. Usually with little effort.
People with cars that are actually fast, especially custom ones, rarely go looking for trouble.
Also I often drive with my arm out the window (if it's down). With a stick shift. Often while smoking (that's why the window's down). OMG I'm just rubbing in your face that driving is easy when you're not retarded (and eating a Big Mac while texting).
edit- Although exdeath is missing one thing, in my experience...the kind of idiots that want to 'race' you rarely understand when they've been thoroughly trounced. Hence why they generally always do their best to pass you at some point. At WOT. Going slow as shit. Loudly. DUDES I TOTALLY BURNED THAT GUY WITH MY MAD FIFTH GEAR PULL YO.
