On November 8th we were driving out of Bolougne towards Wissant when a large lorry hurtled past me blasting his horn. The motorway was switching over from 3 to 2 lanes and he was in the outside lane. I couldn't move over as there was a lorry in the slow lane, I was in the middle lane. He took a chance as the his lane was getting narrower. After that incident he blocked me from overtaking him on seven occasions. Some of this was seriously dangerous. On one occasion the road had returned to 3 lanes and I was trying to overtake in the outside lane when he indicated and pulled out about a metre into my lane. I have excellent dash cam footage of the 7 incidents and have sent some to his employers .awaiting, a reply. However I was just wondering if the French police would accept this and think about warning him.
