Ive had two slow speed wrecks on various machines. The first was on an ATV, back when they only had three wheels, and I tried to stop by putting my leg down on the ground, which caused the rear wheel to roll up my leg and fling me to the dirt. The second was on a moped, the type you had to pedal to start, and I was pulling into a parking spot when I hit that patch of oil/grease thats always in the center of a parking spot, and the front wheel just slipped in the oil and dumped me. Nothing under four wheels for this guy now!
