I always wear a lid on my bike, but I only started because I started racing. I still feel that it is down to the individual and the “less compensation for non-helmet wearing riders” will probably be a large step towards a new law.
When I learned to snowboard at Tamworth (a beautiful alpine resort, just of the A5 😉 ) It was compulsory to wear a helmet for the lessons, but then once you were “competent” 3-to-5 hrs later you didn’t have to, and after a few days in the Austrian Alps, I was crashing my way down black runs with only a wooly hat as protection. I’d love to go boarding again, and I would definitely use a helmet this time.
My change of mind is more driven by my biking/helmet experiences than what is ultimately an incredibly unfortunate series of events, and it is so much easier to track back from a tragedy to the point of no return than to make the correct judgement call every time. If anyone knows the secret to this, please let me know!
