Have a look around this forum. Even this thread. It shouldn't take very long at all to find the prejudice and hatred that exists towards motorists. Even ones that are also cyclists. I used to wonder why people can't just get on. Then I joined this forum and read a few posts. How can anyone expect car drivers to show them any respect whatsoever when so many cyclists express such utter contempt for anyone that drives?
Try a driving forum and see how cyclists are viewed by what appears to be a majority of drivers. That includes some in the heaviest vehicles that we share the roads with, as cyclists.
It can often come down to the contempt that we as cyclists are treated with on the roads.
We don't pay Road Tax -- Nor do car owners/drivers.
We slow them down -- At times we are travelling just as fast as they are.
I don't drive, so come at this from the pedestrian & cyclist point of view. As a pedestrian who was put into A&E by a driver, whilst crossing a road on pedestrian crossing on a road he shouldn't legally have been using. He failed to stop, but the car was found later having been caught on CCTV when the incident took place.
I've been t-boned by another driver, whilst cycling. End result was loss of the job, due to the actions of the driver. He was prevented from going too far because I was on the bonnet, driven down to the engine block by the impact force of a body hitting sheet steel.
