Who would be at fault?
I was on the motorway the other day in lane one, I went to overtake and go into lane two which was completely clear for me to move into - then the car in lane three which was a little bit behind me suddenly moved into lane 2 at the same time as me. Thankfully I managed to swerve out of the way and back into lane 1 avoiding a collision. It made me think who would be at fault if a collision happened because at the time I made the move lane 2 was totally clear, but the person in lane 3 had other ideas. I know if I was the car in lane 3 and saw me move to lane 2 I would'nt moved over.
EDIT; Car in lane 3 was not overtaking anyone, I noticed them in lane 3 for quite while so they were lane higging. Lane 2 was totally clear for at least 3/4 of a mile.
