You're assuming that accidents are equally likely with and without helmets and ignoring OP's point that, on balance, you're better off biking without a helmet than not biking at all.

You might actually be right here. I do not know. Either way, don't expect "I really don't need to cite anything" to convince anybody serious.

Don't understand why this has been downvoted. The research behind helmets is exactly why in The Netherlands helmets aren't mandatory. For one, they reduce the amount of people who cycle. Thus they take a car with higher speed, etc. Secondly, wearing a helmet causes cars to be less risk adverse when interacting with you. Lastly, most helmets are utter crap. They tested various and the majority sold in shops are of very poor quality (don't help at all).

Strangely, in Denmark most cyclists do wear a helmet. To me it's very inconvenient. E.g. where to store the damn thing when going anywhere?
