Hi, This is a weird one. Maybe some of the resident bobbies can shed some insight. Coming home, a police van is ahead of me, doing I estimate 60 in a 40, so being driven quite sprightly. No blues. But, hey, maybe they are stealthing for some reason. Come into a dual lane bit of road (still a 40). Police van pulls behind another car, which is going a bit slower, so I catch up. Police van then moves into lane two, turning right at the upcoming roundabout. I continue going straight on, and do a sprightly overtake of the other car after the roundabout. This is naturally done within legal limits. Next thing I know, I see blues in the mirror as the van has obviously swung round the roundabout and followed me. It overtakes the same car as me, turns OFF the blues, then must be doing a RAPID number of knots to catch up with me (as I'm being law abiding!). It follows me for another 30 seconds or so, before turning into another road. What's going on here? I'd have thougth if they were thinking something suspect about me, they'd have tugged me at this point... (Note: I was in the cage for this. It's interesting that if you overtake sprightly on a bike, other drivers go "Oh, whatever". Do the same in a car and it's "HOW DARE YOU OVERTAKE ME!!!!") Tris.
