you do not have to pull over for an UNMARKED car
Spent an interesting mile or so on a tight country road with one of these filling the motorbike’s mirrors a few years ago (it was a proppa unmarked car)
I pulled over when it was safe to so and the driver gave me The Look followed by The Headshake
A little further down the road there had been a very minor incident and as I waited the police officer came over to me and ‘had a word’. The situation could’ve escalated quite quickly but I remained calm, noted his number and wrote a letter to the local police HQ. A few days later I got a response from the Chief Superintendent apologising for the officer’s actions and also clarifying the situation when being followed by *anything* with blue lights, unmarked or otherwise.
