The one myth they did that I was truly concerned for their safety was when they piled a bunch of lumber and construction material on top of a Volkswagen Jetta and drove around. Having owned one, I had
no confidence that the roof structure was strong enough to support it all. I think they were lucky that it didn't collapse and kill them, even though they wedged a 4x4 in there for support.
