Welcome to the world of extreme sports, where only the bravest (or most reckless) daredevils are welcome.
Stock car racing: where the only modification is the paint scheme Freerunning: because why not just run off a cliff? Underwater racing: where the real challenge is not the speed, but the snorkel. Robot racing: where the real winner is the one with the most hydraulic fluids. Motorcross: where the real prize is a good mechanic.
