I must see them in person. Race car drivers don't count. Nor does it count if they're wearing the helmet for some other reason and briefly entered a car. It must seem like they're wearing it primarily to reduce the risk of injury in a car accident in normal driving operations.
If they're wearing a helmet because I honestly convinced them it was a good idea, that counts. If they're doing it because I paid them or otherwise influenced their decision in some way that isn't "them thinking it's a good idea", that doesn't count.

Why does this make me angry? On the face of it, it shouldn't. I like people doing strange things.
I think it's because the safetyist religion is inherently proselytysing and coercive. Plane seatbelts, face masks, bike helmets, you name it. This tendency is reflected in the phrasing of the question - of course you want to have other people doing it. That's why it makes me angry.
The same reason why I hate leftist politics and gravitate towards MAGA. With leftists it's always "we", "we", "we", "weeeeee". No. Do what you want, but leave me out of it.
I wonder if wearing a helmet makes you feel safer, causing complacency, and actually increasing the overall risk of head injury.
I wonder how many motor vehicle accident sustained TBIs are from the head forcibly colliding with some external object (I.e. able to be protected by a helmet), versus from the brain colliding with the inside of the skull (wherein a helmet wouldn’t make a difference).
@snazzlePop A helmet still helps in the latter case, the point is the lower the acceleration experienced by the head.
Is there some research suggesting that wearing a helmet significantly reduces relative risk of serious injury when driving a car?
Would it resolve to YES if the person you saw wearing a helmet was someone you knew / convinced to put a helmet on, either for safety reasons or for the purpose of this market's resolution?
@TheBayesian Good question. If they're wearing a helmet because I honestly convinced them it was a good idea, that counts. If they're doing it because I paid them or otherwise influence their decision in some way that isn't "them thinking it's a good idea", that doesn't count.
