The audi was initially wrong to pull into box. However that didnt give the cyclist the right to back up scraping down the side of his car.

The cyclist initiated the initial confrontation rather than just doing what most normal people would do and shake thier head and carry on. It was pretty obvious the audi driver knew what he was doing was wrong. knocking on the window and giving him lip is just going to make things worse.

Still the audi driver didnt need to thump him one

Many cyclists do ask for it though. Some cunt came up alongside my car at the lights the other day then leaned on my car while he waited for the lights to change. The cunt didnt appreciate it when i rolled down the window and told him to get off my car. it might be a shitty KA but i keep it clean and dont want some pricks sweaty palm and leg prints down the side of it.
