What a load of poppy cock. All a helmet does is stop a bit of gravel rash on your noggin, and also stop lots of questioned when you are wheeled into A&E with a broken spine, or suspected fractured hip - tried and tested. High vis, lights don't help drivers see you if they aren't looking.
Have you just grabbed that paragraph off google AI ?
My point is not about safety, it is actually about lawyers and protecting yourself legally. In an accident with a car, if you try to sue, the first thing the drivers lawyer will ask is------------were you wearing a helmet. The fact that you broke a leg is secondary to the drivers lawyer.
