I wish more people would take that advice. At times I am glad that I don't drive with some of the drivers I've seen on the roads, have been in numerous near misses while on buses and seen one cyclist after a fatal road collision and helped another after he was sent flying through the air after colliding with a car. He was very lucky given the impact and lack of a helmet, injured but could have been far worse.
It's awful to see the amount of inappropriately dressed/kitted out cyclists on a major route into the city, no helmets, long flowing garments, headphones, no hands, two on a bike etc... It's a major accident spot and another young cyclist was killed just down from me quite recently.
Some people just don't seem to read the road properly, a junction by me, a crossroads, has clear give way signs but I've seen quite a few crashes and can often hear the screech of brakes and cars swerving to avoid each other as some are just not reading the road signs.
Lots of trail bikes and quad bikes being ridden round the roads here at the moment, accident waiting to happen, some don't even look old enough to drive.
