A bit of a close one yesterday afternoon on the Loch Lomond Road between Ardlui and Crianlarich, I was safely over taking a line of cars and suddenly I was then over taken by a Renault Megane Sport car....WHILE I WAS OVERTAKING.....he was on the grass verge on the opposite side of the road throwing up stones and grit at me.....he then lost control as he swung back across the road and collided with one of the cars being overtaken bumping him onto the opposite grass verge, he than loses control as he swings back onto the road......so in front of me I have two out of control cars colliding with each other, wing mirrors and glass bouncing all over the road.....I'm still on the opposite side of the road as I was still in overtaking mode and can't cut in as the lines of cars are all breaking.......the Megane does stop as he's a runner which gave me space to pull in front of the car he just hit......shat myself to say the least.
