I loved driving a sportbike with a tune and an unrestricted racing exhaust, if I revved it just right I could make it backfire directly into your rolled down window

This is a genuine question and not intended as an insult: do you have a personality disorder?

Eh, you ride a bike long enough and you're more or less forced into this level of hostility toward the drivers around you.

Maybe a bicycle. If you ride a bike long enough on US roads - you probably have a death wish.

Given the gun ownership rates, I wouldn't be surprised if someone gets shot for doing obnoxious shit in a road rage incident.

Cute, but you haven't really lived until you've ripped an apocalyptic burnout in front of the dude that's been tailgating you for the last N miles. Trading ~1k worth of tire wear for coating the front of their car with rock chips and molten asphalt is a damn good deal.

$1K? And I thought my tires were expensive, damn...
