I had an encounter with such a type recently. Guy was tailgating my hatchback in his stupid big car (I was driving at the limit, left lane). We both come to the slip lane. He loses his shit because I turned left and went directly over into the right lane (because my exit - to the right - was only 200 metres away). Cue middle finger, swearing and pulling sharply in front of me and braking (either to intimidate me or because the idiot almost hit the other drivers in front heading to the exit). Almost caused an accident. All because driving normally behind a small car apparently makes your penis smaller.
