for me, seeing a family of mother, sometimes father and kids on the road biking and parents have no helmet and kids' helmets are so far back on their heads that they might as well not be wearing them. Don't people have ANY common sense anymore? The helmet has to worn correctly or you might as well not wear it. Here is a good checklist for helmet fit. There are lots of You Tube videos if you want to spend some time, Remember, 3 minutes watching a video may save you or your child's life.
Second pet peeve
for me, cyclists passing another cyclist not in their group. I often ride solo and I go slow. Often times large groups of Lance wannabes pass me at break neck pace and way too close. When you bike slow, especially up a hill, maintaining a perfectly straight line is hard to do plus I have to look at passing cyclists making my journey not so safe. The passing cyclists often do not announce that the are coming, particularly true of a lone fast cyclist. They just buzz by scaring me. Not sure why cyclists whine and complain when a car buzzes them but have no idea that a cyclist can buzz another cyclist. Hey slow down Mr Speedy, so you lose 10 seconds off of your ride, where are you going anyhow that your time and speed actually matters? Sometimes I feel I need an engine when getting passed.
Third pet peeve
for me is when a car passes me. What can possibly be going through the motorist's head when he or she passes me when I am going up a hill and there is a huge curve in the road. Ya'd think the car might slow down and wait. No the cars blast past, I know I will witness a head on crash someday.
Today a car squeezed by me when oncoming cars were actually passing opposite me. I could not believe it. I don't get the need for speed when most of the motorists passing me probably waste hours a day checking email and Facebook. But losing 10 seconds behind me is an impossibilty.
