I personally don't, I feel less safe wearing one. I can't locate cars as accurately with audio with one on my head, the extra weight makesy head turn slower, and I think subconsciously left often. Drivers pass more aggressively and illegally (most drivers passing break the law here that requires a meter seperation when passing a cyclist, but they break it 'more' by coming closer when I wear a helmet).
I'm not aware of any study that says this. The most I've ever read is speculation that wearing a helmet might lead to more accidents, but that's not the same thing, since accidents with head protection are less likely to result in catastrophic head trauma and death. Could you maybe drop a reference link or two for this claim?
You should read this instead: https://www.vox.com/2014/5/16/5720762/stop-forcing-people-to...
Why? Because it's an meta analysis of a bunch of actually rigorous papers written for the general public.
My original source was a blogpost written by some guy with an opinion. I promise you I'm not lying that's what it said, but I wouldn't trust the statistics he had to not be caused by some quirk like "people in safer to countries to bike are less likely to wear helmets". I can't find it again, sorry - probably because google has gotten so much worse at surfacing blogposts in the last few years. You'll just have to take my word that I wasn't lying when I said I saw such statistics (or google more yourself, I didn't try that hard, but at some point googling for statistics that support your view is unfair cherry picking of evidence).
Doubtless in case of a collision you’d be better off with the helmet, but at a high enough speed it won’t matter anyway.
I used to play basketball with a personal injury lawyer who flat-out stated that the % of situations he’s seen where a helmet actually helped was very small.
I don’t wear one for many reasons; and I don’t judge anyone else’s decision.
I've heard that too. If it's true, could the causality be the other way? As in, people wear a helmet when the chance of accidents is bigger.
When I road bike on open roads it's both fast and higher chance of accidents, so I wear a helmet. Same with downhill cycling. But when using a city bike, I bike slow in the inner city, and don't have a helmet.
A rear view mirror might change my decision, I keep intending to try some of those out.
It's modeled after this one: https://www.efficientvelo.com/home/safezone
The key component is the flexible, stays-where-you-put-it arm. Safezone is repurposing an industrial product called "coolant hose" - a 1-ft length costs less than $5. Epoxy a small mirror to the end, and attach it to your helmet with zip ties or velcro straps.

It's simple to clip on, and stays put once it is, I've been using this mirror for over 5 years and feel uncomfortable riding without it.
Bike helmets are no impediment to vision or turning one's head.
What I'd like is a cam linked to the police that would auto-ticket anyone passing too close. I would gladly sign an affidavit confirming the infraction.
Completely untrue. Bike helmets do increase the risk of concussion but decrease the risk of other serious injuries or death.
