This video clip was shot in Morocco. The motorcyclist reaches speeds of up to 87 mph on his home-built contraption, adopting the weird and almost uncontrollable position shown.
One pothole, one undue bounce, and he'd have had no control whatsoever to stop himself crashing. If he'd done so, I don't think he'd have qualified for the 72 virgins Islamic martyrs are supposed to receive . . . but I daresay he might have found himself handed over to 72 deceased traffic cops, to teach him a lesson!
