Why would a police car do this?
I was driving down what used to be the A1. I had my cruise control set to 60mph. I notice a police car behind me, do the mental panic even through I'm not breaking any laws that I'm aware of.
It pulls into the other lane (only 2 lanes) as if it's going to overtake me which I think ok but weird as it's not flashed at me to pull over or does it have it's blues and twos on.
It then stays there for probably 20 seconds until a lorry appears on the other side of the road so approaching the police car,then it pulls back in behind me. Stays behind me for maybe 10mins then pulls into a lay-by.
