Well, I wouldn't say that the biker is necessarily at fault here, Once he became airborn, he had no way to control the bike. Jeep driver could have stopped. It's off road, so I'm not sure if jeep's insurance would cover it, and dirt biker prolly got nothin' for insurance. Either way, jeep hood's probably only a couple hundred bucks. Dude's lucky the jeep wasn't 3 feet further along.
Even another foot would have been bad. I think the guys standing at the top of the hill should have waved the riders off.
