Motorcycle crashes too. I'm mostly worried about my teeth and my brain bouncing around in my skull but Brad and Kali showed me a few street helmets where the rider was going so fast that the pavement essentially sanded through helmet layers - that's never going to happen the same way twice. It's cool they collect crashed helmets though to think about things like how the layers come apart.
