The Bumper Car Psychos

All Things Considered:

The "Bumper Car Psychos" are easy to spot. While the other bumper cars at New Jersey's Keansburg Amusement Park spin wildly from one collision to the next, the Psychos cruise gracefully around the track, grinning from ear to ear as they slam their targets into the wall.
That's not the only reason the Psychos stand out. Keith Van Brunt and Tom Mgerack both weigh upwards of 300 pounds, and both are heavily tattooed. They've been riding the old bumper cars here every Friday night since 1996. Someone started calling them "psycho" the following year, and the name just stuck.
"For me, it's kind of like an adrenaline rush," says Van Brunt. "You know, some people jump out of planes for adrenaline rushes? Bumper cars, that's like my adrenaline rush."
For Mgerack, the ride is an escape from mundane problems: "You're concentrating on what's going on in there, and you're looking to who you're going to go after next, or look to see who' s coming to get you," he says. "Keeps you out of trouble."
The Bumper Car Psychos always ride the same cars: Van Brunt likes the blue police car, while Mgerack prefers the red one with the Harley-Davidson logo. The men have learned to maneuver these classic cars with uncanny precision, even through the floor's coating of kerosene and graphite that keeps the ride slick.

Awesome.  I love driving around in a bumper car and just blindsiding people.  These guys do it all the time.
