Soldato
I used to cycle a lot. Out on a club run one day and the guy in front of me stood on the peddles on a slight bend on a wet slippy white line. The back wheel spun and jumped to the side, he lost control of the bike, and went head first onto, and along the road. I'd say at about 18-20 mph. That was about 18 years ago, and to this day I can still see his head slide, forehead first along the road.
We called an ambulance and he was taken to A and E. Thankully, he was discharge home after a few hours. He was off work about a week and apart from a scar on his forehead did not suffer any serious harm.
However, I was the one who saw the incident, I had to go to his home to tell his wife what happened and saw the look on her face when I did. He also had 2 daughters aged about 6 and 8 at that time.
I saw the crash and his helmet, which was sitting on his TV would have taken the brunt of his fall!
I have no problem whatsoever with people taking risks. The problem I have is that most who do have made no provision to sort out the mess they'll leave behind if something goes wrong.
That's the thing in cycling, there are situations where helmet or not won't make a difference, but it's the smaller situations which are helpful. I commute daily (30 miles per day) on the road from West London to the city, and I have had a couple of incidents where cars have hit me (thankfully I was at low speed) where I hit my head and the helmet took the fall.
I personally don't see a reason why cyclists should feel exempt from wearing a helmet if they make a choice of cycling on the highways, the usual excuses ("it's uncomfortable" "It does not look cool") I feel are invalid.
Some protection is better than none.
