The final segment starting at 6:00 makes me think that he can wear as much leather as he wants protecting his body while sliding over asphalt when he's anyway intent on braking with his face and chin.

  “There are many things you can point to as proof that the human is not smart. But my personal favorite would have to be that we needed to invent the helmet. What was happening, apparently, was that we were involved in a lot of activities that were cracking our heads. We chose not to avoid doing those activities but, instead, to come up with some sort of device to help us enjoy our head-cracking lifestyles. And even that didn’t work because not enough people were wearing them so we had to come up with the helmet law. Which is even stupider, the idea behind the helmet law being to preserve a brain whose judgment is so poor, it does not even try to avoid the cracking of the head it’s in.”
