My supervisor for my masters was vehemently anti-helmet. Not anti-helmet law, anti helmet - was so viscerally opposed to them that he bought a tricycle to circumvent NZs mandatory helmet law and then intentionally goaded police into writing tickets so he could then say “the law says bicycle and this is a tricycle”.

Note that every study has shown that wearing a helmet reduces the likelihood of permanent injury, so while you can complain that helmet laws are bad, this guy was an idiot and believed that the act of wearing a helmet itself increased your likelihood of injury.
