Muscle car envy, or just plain stupid ?

Well, when people are young or just young at heart they like the process of blowing the cobs off the valves in little street competition.
Lots of these type people probably either have great lawyers /money, are stupid or were raised where no one lives.
Living in nowhere, you can do it. Living in town, you can go to jail or have your hands chopped off for attempted murder of oxygen molecules.

I'd just ignore the idiots if they are going to risk their license and involve you in an in town street race, considering the laws these days.

Screw em. When I was a kid, I would race anybody in anything. We raced a citation against a yz80 on a backwoods straight. yz beat me to about 75 mph. Running down the highway and the rice burners came up, we would ask them to be sure and wind their rubber band first. Then we would blow carbon and tire chunks onto their windshield and hold it on the floor for 2 miles to make a point that we were drivin gas burning piston clanking smoke belchin air polloutin four wheeled buggies from detroit city.
