There is no doubt that using a jammer is not a good idea for all the reasons postulated here, and drivers should learn to obey the speed limits, however the real debate should be about the imposition of unrealistic speed limits. For example there is a 20mph limit outside a local school. All well and quite justifiable you might say, except this school is a boarding school with some day pupils, who never walk to school anyway, is set on a very wide road, and with no more than half a dozen pupils walking by at any time time of the day (or night). I often come across other limits on roads on which I wonder why they have them there, no wonder motorists go faster on these roads, then ignore a limit where it is really needed.
I remember 'jamming' a Police speed trap in the early '70's when I was younger and sometimes pretty silly. I parked my car in front of a light blue Morris 1000 van, with the back doors open and a large 'box' inside. Eventually a head popped up from the front and waved me away, which I eventually did with an appropriate acknowledgment using 2 of my fingers. The next day a couple of Somerset's finest were knocking at my door and a couple of weeks later I was up before the magistrates accused of 'obstructing the police in the execution of their duty'.
I had nothing to lose, so defended myself, in my best collar and tie, (as you do), and managed to convince the bench that I was only checking on why a van should be parked on the grass with its' back doors wide open and left, with an acknowledgement, when told to do so. Praise be, they believed me, and let me off, but it was certainly a wake up call not to indulge in that sort of behaviour again.
I rather suspect the gentleman in the RR may take this onboard in a similar way, although he has had a lot more publicity about his little misdemeanour.
