I've just been out to get some petrol for tomorrow and on my way back, I pulled right out of a junction fairly quickly, up to 30 in no time, then foot off and was sitting at about 32mph. (on the speedo)
Up ahead, there was a police van (meatwagon) in a side road which had been sat there the whole time. As I was approaching it pulled out a couple of foot into the road to make me move over into the other lane!
I carried on driving & watched in my mirror as it pulled out & started following me. Around 200m up the road the van had its lights on, so it pulled over for it to pass, but it pulled up behind me!
I sat there wondering what law I'd broken & the policeman came up to my window & told me that 'even though I had a fast car, to slow down'
I said sure, no problem & pointed out that I didn't break the speed limit & wasn't driving dangerously. Once again, he said 'just slow down' & once again, I said OK sure.
I then asked him if he was the driver of the van, and he said 'yes'. I then asked him why did he pull out into the road on me & he said 'to get you to slow down' I just sat there & chuckled while he walked back to his van.
I know it probably sounded like I was doing more than 30 from the acceleration and the NUR spec, but is it police procedure to do this sort of stuff if they 'think' you're going too fast?
