Many years back on a trip home from the the Chunnel, the traffic slowed ahead down to a crawl then a stop, we were in the Mog with the top down and on the inside lane, when a car passed at what could easily have been over the ton, stones flying everywhere, it gave my good lady quite a fright..me too..! I reckon the traffic slow down was a police tactic to try and catch the nutters in the speeding car... Scary stuff indeed..!!!
