Driver held down the horn for no reason then drove along a busy road with two lanes hanging out of her window and shouting abuse. After we pulled over the fat beast driving shouted over everything I said just repeating "You nearly caused me to crash into that cyclist."
Eventually I managed to tell her that she was in the wrong and that the lane I was in can go straight on. Long story short she assumed I was turning right, didn't check her blind spot, nearly drove into me then swerved back into her lane and nearly took out a cyclist. She then pressed her horn and started shouting abuse at us for her mistake.
I agree. Terrible driver.
