Many years ago I once had the pleasure of pulling a Panda car over for speeding! I had been going through Hounslow West at a tad over the speed limit in my Marina TC when a local plods pulled me at the traffic lights. He told me to pull in across the lights which I duly did and he then came to the car an gave me a stern talking to about the errors of speeding. I was suitably apologetic and we left it at that. He went back to his car and shot off like a scalded cat ! I followed him and at 40MPH he was still pulling away, (the limit was and still is 30 in the town centre), Well at that time I had a CB Radio in my car and part of it's kit was synthesiser siren with about 30 different modulations on it, At the time the Police were still using the familiar two tone siren so I switched mine to the now widely used American police style and gave him aquick burst while flashing my headlights. The effect was extroardinary, he braked sharply and pulled to the side of the road. I pulled in behind him and this time I walked up to HIS car. He looked up at me somewhat bemused as I asked him what speed he was doing as I thought my speedo must be faulty! He asked why I thought that so I said that mine was showing 30MPH but I couldnt keep up with him ! I couldnt see any blue lights flashing so I KNEW he wasnt on an emergency and of course being a POLICE officer he would NEVER break the speed limit! Would he? His face was a picture, His reply was sort of ,Oh err, yes well, umm, Ok Fair enough, He then grinned and asked where I'd got the siren from and we got onto talking about CB Radios which had just been legalised ! I didnt mention that the synthesiser could also EXACTLY replicate the UK police sirens as well as the American ones! He finally said "Well we have both learned something today havent we? " After that whenever we saw each other on the road we'd pass with a cheery wave and a flash of headlights! Over time we became good freinds but we lost touch when he was posted to another district of London. I often wondered what happened to him.
