on the way back from Crieff (well, was Inverness, but went back via Glen Coe!) was in a queue of cars going at a steady 55 mph.
guys in a mondeo over take the queue.
was just past me when he hit the brakes...
next thing the car jumps in the air abit and a 2 foot boulder comes through the back of the car!!
the boulder had been sitting on the other side of the road and he had gone right into and over it!
took out the back right wheel/suspension and ripped off the bumper in bits. quite a crunch!
didnt see the front of the car, but did see some steam/smoke in the rear mirror

i avoided the bits the boulder removed

unlucky to the guy
