Driving home the back way from Yarnfield this evening, there was a white Mercedes (a big one) in front of me. Reg No. AT 51 CAZ. The driver was so far up the arse of the car in front,he/she/ it could see the flies hitting the front number plate. If the driver of the car he/she/it was following had to bung their brakes on quick, there would've been 1 hell of a smash. They kept getting right up close, then had put the brakes on. Bloody stupid, personally, I would've slowed down so it really got on their tits.
