Steel is real, man. It'll bend, not break.

But in seriousness, yeah, I was following very closely behind a fellow who snapped his fork jumping over a bump in the road. I almost went over him. Despite the helmet, he lost memory of the accident. I called an ambulance for him and left my number. He called me the next day asking what had happened.

It was a nice aluminum frame, looked in good condition. Always check carefully for hairline fractures when buying a used aluminum bike.
