> Why not wear it?

Car drivers often get head and brain injuries if they are involved in a collision with another car or with a tree/building. Do you wear a helmet when you drive? The helmet doesn't add almost any inconvenience, is reasonably cheap and light, as you say.

Unless you're on a racetrack or driving a test vehicle, probably not.

For the record, I do wear a helmet on a racetrack in a car. :-) It adds major inconvenience, but the general risk on a racetrack is greater because you're pushing the vehicle to its limits.

The risk/inconvenience ratio seems OK for me when driving a car without a helmet but not for biking without a helmet. I'm not advocating for mandatory helmets. But I would feel very uncomfortable if they would be banned.

I think most people will disagree with you on how big of an inconvenience a helmet is. At least I will.

In Europe most people didn't even wear helmets when they went skiing (on-piste) until a few years ago. Now pretty much everyone does, but it's one more thing you'll carry with you everywhere you go. And on warm days I sometimes have to take my helmet off in the gondola because it gets very warm.

Yeah when I visited Europe I didn't wear a bicycle helmet either. American cities are a different story, with poorly designed roads and poorly designed vehicles with large blind spots around the A pillars especially.
