A big danger to others on the road, especially towards motorcyclists. Often fails to indicate when turning/changing lanes and often denies liability or accepts fault for his own actions.
Very rude driver denied repeatedly banging her door into my car, despite the fact I was watching her do it. Then swore at me, made a rude gesture and drove off. All in front of the young child in her car. Classy. I pity the child and fear for it's future if that what it is exposed to.
I was cycling to work when the driver tried to run me off the road in Finsbury Park as we went through road works. He told me afterwards that a driver had been trying to overtake him, but I'm not sure why that gave him the right to almost kill me.
An ingenious place to park when there is nowhere else left on the road to go
