This type of Police tactic must be getting more popular.
I was driving the Supra a few months back and was behind two other cars which were both doing about 70mph on a dual carriageway.
I had this car behind me that looked as if I were towing it, as it was so close to my bumper.
Anyway, the two cars in front pulled over, I put my foot down and overtook then pulled in to the inside lane. Then the guy that had been tailing me, put on the blue lights.
I started to pull in and he just flew straight by.
I;m not sure if they suddenly got an urgent call or if they were just bating me and changed there mind, but it did seem a little odd.
