It happens every 5th car down here! I had one guy so intent on driving at 2 feet behind my bumper on the way up past oxford, I tried all the subtle things, flash of the hazards, ease off a little then speed up but he just didn't get it, he really didn't like it when i gently dabbed the brakes to show him my brake lights, he started flashing and all sorts (inside lane totally chocka and outisde lane was moving the same speed as us, and car in front of me 3 seconds away) not to mention the cloud of smoke that came from his wheels as he over reacted and locked his brakes! I just don't get why people are like that, they endanger themselves and more importantly me :-(
Then again up in brum, maybe people just like blue pugs or something (company loaner for two days)
