I definitely get given more room on overtakes, if I don't wear a helmet.
I agree somewhat with that article, everyday commuting shouldn't require a helmet, as the article says there's more chance of a head injury as a pedestrian.
I mean if I get hit by a car that's travelling at 30+ mph, I doubt very much a helmet would save my life.
I do think they're useful for children, as they're most likely to have a slow speed impact with the ground, which helmets are useful for.
I take issue with people preaching saying, "I was in an bicycle accident, and a helmet saved my life". How can you be so sure? I've seen a shot put land on a child's head before, who survived with minor concussion. I've also seen someone cycle into side of the van, doing close to 40mph downhill. We had to call an ambulance, but he didn't sustain any long term injuries.
Having said all that, I wear a helmet as I get abuse from home and work if I don't
In other news; I adjusted my cleats at lunchtime, moved them a lot further back. I only had time afterwards to quickly go round the carpark, but it felt like my positioning was more natural. I did have a bit of hard time clipping in though, but I guess I'll get used to the change soon. Hopefully get out for a quick spin after work tonight for a real test.
