True... But they wouldn't let, lets say Erik Koston go down the slopestyle course after 4 hours of riding a snowboard. Riding a motorcylce is completley different than riding a sled, the weight, the clutch, the speed... Everything. It seems very convienent that this throttle became stuck, not sure that would have happened to a more experienced rider. I love extreme sports, thats what i've based my whole life around but there comes a point when something is sick and progressive to something that is stupid and outright dangerous. You can pretty much expect multiple people to get messed up flipping a sled. They don't need to remove the event, just revise it.
