Killed a beat-down 240

Not really the best story, but I figured since I'm new and don't really have a lot of posts I'd share.

I wasn't looking for a street race, and my car isn't even modded so I don't know why people think I'm out to race, but this guy in his rusted out 240 kept revving the crap out of that bitch and grinning at me. At the light, I took off slowly, but when I saw him get on it I went WOT. Pretty much waxed him, but I know that's not really too braggable...

What makes these kids in old, slow cars want to go around racing everyone?
