Is it possible the police can check your speed when they are coming towards you?
I was on a s/c this week doing about 43ish, and a marked X5 was coming the other way, I clearly saw the passenger copper then lift what had to be a camera and look directly at me 
Have they got the stuff to do you for speeding now when they too are moving and coming towards you and not just when they’re following??

obviously they can do you coming towards them if they are stationary but i find it hard to believe they can do it if they are travelling as well
Oh yes, Vascar! (Google it)
Many police cars had Vascar fitted as far back as the late 60’s and I am sure they have similar devices now. Vascar can be used anywhere, copper on foot, in a car, motorbike or even helicopter, it works out the speed over a set distance between known points on the road so the car can be going in either direction.
Many roads used to have white squares a set distance apart, these were originally for Vascar speed checks.
I would have thought they would have given you a tug if they were going to do you surely?
43 isnt really too bad aslong as it was a 40+ speed limit road.
Yep, the ANPR fitted cars certainly can. I was in a car (not driving) that was pulled over by a copper coming towards us as we rounded a bend, within about a second of him being in vision he had the blues on.
Pulled us over and the speed was printed clearly on the screen.

They clocked a motorbike doing 166mph, you don’t think they were chasing it do you 
Someone explain the science to me? Surely the speed of the police car would affect readings if the police car is going at 70mph it will take the same reading as it it was going at 40mph?

Computer knows the speed of the police car and deducts it from the total impact speed recorded (impact speed is the combined speed of both vehicles) and as police cars have calibrated speedos then it is acceptable within certain tolerances which have to be taken into account if a prosecution is to go ahead
i do believe they used to be able to clock your speed from the opposite carriageway of a motorway, go to the next junction, do a huey and come after you , stop you and show you your speed with vascar…

It’s a simple equation of time over distance, the vascar system is put on the distance part when the offending vehicle goes through a fixed point, then when the police vehicle goes through the same point it puts on the speed part. Then the same happens but the other way round on the next fixed point, the system then works out the speed difference between the two points. See simples!!
