Driving back from Dorset yesterday, on the M3 and a piece of lorry (fibregalss rounded bit, that sits on the top of the front body ) flew off a lorry to my left, caught the wind and literally missed the car by inches, if i had been a foot further back than it would have been in the windscreen. Luckily it missed all the cars and landed on the motorway, where a land rover run it over! Me and the missus went silent for a while!! [-o<
