You know, taking things over jumps can go wrong. Motorcycles, bikes, cars — whatever. But if you want a chance for things to go VERY, VERY wrong, you really gotta kick it up a notch and take a semi over a jump. If you live, you can brag about it forevermore. If you fail, it’s unlikely that anyone else in the vicinity will survive, so there’ll be no one left to mock you.
And remember: only survivors can testify against you in a court of law.
