Jerry Seinfeld, on helmets and helment laws:
"...Skydiving was definitely the scariest thing I've ever done. Let me ask you this question, in regards to the skydiving: what is the point of the helmet in the skydiving? I mean, can you kinda make it? You jump out of that plane and that chute doesn't open, the helmet is now wearing you for protection. Later on, the helmet's talking with the other helmets, going "It's a good thing that he was there, or I would have hit the ground directly."There are many things that we can point to that prove that the human being is not smart. The helmet is my personal favorite, the fact that we had to invent the helmet. Now why did we invent the helmet? Well, because we were participating in many activities that were cracking our heads. We looked at the situation. We chose not to avoid these activities, but to just make little plastic hats so that we can continue our head-cracking lifestyles.
The only thing dumber than the helmet is the helmet law, the point of which is to protect a brain that is functioning so poorly, it's not even trying to stop the cracking of the head that it's in..."
On the other hand you quite often encounter motorcyclist who do not, or would not if they could, wear a helmet.
