I think what happened is that when it hit the post or rubbed the gate the wheel got jerked out of the drivers hands. Since it hung up on the right the wheels veered right, and as it is a front wheel drive vehicle (not to mention the forward momentum) the right tire grabbed the gate leaning up against the fence and it climbed up. Who knows what kind of traction control it has, but it might have sent all the power to the one wheel that was grabbing the most (probably on the gate) also the driver probably freaked out and jammed on the gas as well.WTF? how??
