helmets are really useful if you are riding slow too, I was pulling out of a driveway, there was a little bit of black ice that I didn&#x27;t see, my front wheel went out from me and before I knew it I was down: could not react, one second I was upright, the next second I was on my side and yes, my helmet was cracked by this fall (hit the side of my head on the cement), if I didn&#x27;t have it it&#x27;d have been a much worse day than the very mild headache I got from it.<p>I really don&#x27;t understand all these &quot;helmets don&#x27;t help&quot; folks, having ridden motorcycles and bikes all my life you would not catch me dead without a helmet: a helmet is not an invulnerability cloak but in the end if you fall down and hit your head and you don&#x27;t have one, you are not going to be in a good place, whether you are going at walking speed or 30mph.
