You got to give him this much, it's impressive.
If your willing to hammer your car and put yourself and others (he had a passenger in it) at risk, away with you. Personally I wouldn't. Things could go wrong very fast.
Can't see why people are annoyed with him because he did it in an Impreza. You'd swear there's a shortage of them...!!!
Would love to have seen his face when the airbag went off on landing though. I'd say there was a fine country smell in the car...
