A few weeks ago I was cycling from Dover to London with 6 other riders. We were coming through a Southeast London suburb when a car tried to overtake whist we were going past a traffic island which significantly narrowed the road. We remonstrated with the driver, shouting etc.
The car stopped and the driver and passenger got out and started using very threatening language and their body language was highly aggressive.
I was commuting home through Bristol earlier today, and had just pulled off from some lights. I slowed down a bit to let a cyclist ahead of me pull around a parked car when some twat lent out of a car and hit me. My response was to shout something I won't report on the forum. Now, I'm not going to pretend it hurt, and nothing really came of it, though when I passed them at the next lights I got some grief.
