Sometimes ragdoll physics can actually prove more natural. Sure, most crashes don't send you floating and flipping effortless through the wind, regardless of the laws of gravity, but those crashes aren't nearly as fun.
Take this video, for instance. In reality, this guy would've likely fallen headfirst and spend hours trying to find his brain on the ground -- not because it fell far, but can you imagine how hard it is to find something when you lack cognitive function? Thankfully, we don't have to worry about such philosophical queries; instead, enjoy the video embedded after the break.
