If you don't like clicking on videos, I'll summarize as best I can: Holy shit. It's basically a mashup of Big Wheels, Mario Kart and natural selection. This clip was filmed in New Zealand, where the sport of drift-triking apparently originated, presumably as a government initiative to thin out their population of young men. That said, I'm pretty sure this is what we all imagined our Big Wheels should have been capable of, back when we were kids, tear-assing around, hauling on the shitty handbrake for all it was worth.
If you're interested in getting into the sport yourself, first, please buy some goddamned shoes. After that, the only other equipment required is a helmet, fully paid foot insurance, and a drifting trike. There are a few guys out there who'll sell you those, but it seems that most drift-trike enthusiasts make the things themselves.
But Can It Wail into a Ditch?
Oh, I'm pretty sure it can. I imagine it takes several weeks of practice just to get good enough to choose which ditch you wail into. Though it looks like the learning process is probably quite a bit of fun, so long as you have the right safety equipment.
Holy shit, New Zealand.
