Was on a motorway today 3 lanes I was in the left lane, massive lorry in middle lane, lorry driving at the side of me starts indicating and moving over to my way, I used my horn to let him know I was there, still starts moving into my lane and then when I tooted again he blares his horn for a silly amount of time back at me, his own stupid fault completely by not checking mirrors. He was an inch away from totally wiping me out and causing a fatal accident, my heart was beating really fast I was really shaken up by it. I noted the name of his van and time when I pulled over shortly after, after I'd taken the slip road. It's happened before a few months ago similar incident I had came off slip road and a woman starting coming over to my lane to the point I had to swerve back to the slip road. I drive this road everyday to work and feel it's only a matter of time before one of these idiotic drivers seriously cause an accident with me or someone else involved and it really worries me. Im a sensible driver never caused an accident or been close I drive at the speed limit not slow and not not over. I drive a little car and I feel like that angers people! Should I report this idiot from today or leave it?
