So, yet another reason to implore folk not to call out, gesticulate, abuse and generally invite trouble. Only a very minor percentage of people will react like the angry man in the clip, and as posters have made clear above, many commuter cyclists are neither equipped nor disposed to backing their words up when toe to toe.
The angry man was wrong, but he wouldn't have got out of the car if he hadn't been called a w*****.
I disagree. If you don't speak up for yourself these people will take more and more liberties. You don't have to be rude or violent, but it's perfectly okay to stick up for yourself.
