Yes, great point. I wear my helmet not because of fear of getting hit by a car (because, let's face it, if a car hits me, there's likely a lot more to worry about), but mainly because of all the times I've fallen on my own (from losing my balance, swerving to dodge something, getting a tire stuck in the trolley tracks, etc), my head has almost always made contact with pavement. My helmet has saved me from -- at the very least -- a painful bump on the head, and more likely from concussions.

Also if you get a decent helmet and you ride at a decent clip, 35km+, it actually can be cooler. Your coiffed hair however may suffer.
