I’m sure it could also be used the other way round, cop pulls over a motorist who he knows has been speeding but hasn’t got an accurate fix on and this device then supplies the evidence, I know which is more likely to happen to me :w00t:
Im sure he wouldnt have been ‘Hauled into court’ over 42mph in a 30 zone! 
i know…:rolleyes:
Much prefer cameras to black boxes that take an average speed and record everything…
If you deny you were speeding and the scamerati say you were, you’ll end up in court, plus and Sunderland is full of 30mph dual carriageways, it’s a scam.
may i sak somthing?..
ive always wonderd if the police speed detectors need calaberating?(sp)?
and how often there done…
cheers black Rat!!!
smiled:).
Gatsos are not accurate there are too many reflections to be so…this is why they have the markings on the raod which are supposed to be the main indicator of your speed, so always check them if you doubt their accuracy…
The laser devices are even less accurate. They are OK if they are fired at the front, flat, area of a car but they suffer from slip error. This is where the laser is pointed at the side of the car and moved along the body as the car drives past. This can add or deduct a very significant speed, sometimes as much as the original speed of the car, doubling its speed.
Consider the same effect on a bike with a fairing . . . there is no flat surface, the only area to aim at is the front fairing which slopes away and down the side of the bike. . . . hence why MCN made such a big issue out of this when it was discovered that some (all ?) laser devices and GATSO’s were not type approved for or tested on bikes. Even aiming at the headlight doesn’t work as it does in cars because they are so small and again slope away down the fairing.
It’s serious as for example E when he was caught at an alledged 71 could in fact have been doing 48 mph which would probably be a 3 pointer and £60 fine and on your way son . . . but instead he’s got a more serious problem.
If the laser device picks up an echo from the top of the front tyre (or top of the rear when used ‘from behind’) the reading can of course be double that of the bike itself. These radar devices have not been tested against motorbikes…
