Haha, I love a good debate, firstly it won't simply snap off, it's made from sheet aluminium, not cast, sheet metal is rolled with the aid of heat, there for it's quite a strong material, the way you brake sheet metal is through metal fatigue, this is when a material is bent repeatedly until it snaps, as the video above demonstrates, the idea of just driving along and it just suddenly just snapping off is just plain ridiculous.
