Cyclists irritate me where I live in the Dales. There are lots, who cycle in all the gear two abreast on hilly roads, significantly slowing journeys and wobbling all over the place both up and downhill. They also irritate me in cities where they weave all over, ignore signals, flip flop off pavements, ignore cycle lanes.
BUT, here's the thing, they are not ALL cyclists, they are just some of them.
Just the same as not ALL drivers behave the same.
It is true however that some drivers are horrendous. They don't irritate me they infuriate me.
Driving using a mobile phone for any reason leaves anyone out of control of a dangerous vehicle at any speed.
Driving without consideration for anybody else, as too many drivers do, is dangerous.
Drink driving, drug driving; old people driving when way past a safe age.
There are horrendous drivers who risk the lives of other drivers, passengers, cyclists, pedestrians and animals.
A little bit more responsibility and consideration is needed then perhaps by both drivers and cyclists.
