There I was, trundling along at about 15 mph. 20 yards ahead, red TL, with stationary car indicating left. I wanted to go straight on, so I adopted primary. I'm now 15 yards from the stationary vehicle. A stupid cow in a car starts to overtake me. Where, in hell's name, does she think she's going? There's a red TL and a stationary car ahead - there's no where for her to go!! Just then, a car turns the corner at the TL and drives up towards her. So, she pulls in .. straight over the place where I would have been had I not braked sharply and swerved. I would have been splattered. So, when we come to a halt at the TL, I ask her (without any swearing) what on earth she thinks she's doing. She completely blanks me. Her eyes don't even flick in my direction. She just sits there, hanging on to the steering wheel, gazing out of the windscreen. I raise my voice, and ask her again. No response. So I get angry, and bang on the windscreen a bit. Still no response, so I give up. When I talked to my wife later, she said that the girl was probably terrified; a great hairy man shouting and banging on her car. Good! I thought. I was quite terrified for a moment or two when she started to swerve into me. Maybe next time, she'll think and look beyond the couple of yards in front of her car.
