Scamera vans

I was told by the time you've seen them it's too late. That said I've had a few moments with them that have come to nothing. Fingers crossed for you.

I think they are laser controlled and it requires an operator to point it at your car. It is an instantaneous speed they get.

Instant. So your 25mph tactic was, sadly, pointless. I have my fingers crossed for you that supper was not expensive that evening.

It takes several hundred readings over a third of a second, measuring the time it takes for light to bounce back to the gun and dividing it by two to get the distance to the car. 

Is that true? I always thought that they used Doppler to detect speed.  Or am I thinking of fixed cameras?

Interesting. The Wikipedia page (fount of all knowledge) on LIDAR suggests that it measures return times and wavelengths, so I guess it must use a combination of the two methods (or at least LIDAR per se can do). You live and learn.

Do you have existing points? Speed awareness course a possibility?

Would be annoying to sully a 23 year clean sheet!

You might also benefit from the 10% +2 rule which would require you to be travelling 35mph or more. If your dial was reading 35 chances are it was slightly over reading and your actual speed was between 33 & 34mph. Not all forces use that rule but iirc from my letter I received from Leicester Police for running a red at Fosse Park last year, it is the general guidance given by the Home Office.

One guarantee I can offer is that the laser would have spotted you several times before you noticed it doing so. The human brains ability to decipher what the eye sees is sadly no match for the speed of light!

I thought the speed had to be over a certain distance but that may be old/past practice.

I re-learned stuff I'd long ago forgotten, I'm slightly embarrassed to say.

This is my understanding - when I got done by one (sullying a 32 year clean record), it was suggested I ask for the photo, the operator's certificate and the record of calibration for the equipment as they get too overwhelmed to answer all such requests - unfortunately mine was in the batch they did get time to attend to!

I didn't get the option to go on a course and the initial letter suggested I might have to go to court with the threat of a ban (88mph on a dual carriageway), which was why I thought I had better do what I could to see if there was a chance to dip out of it - in the end it was just a fine and it didn't increase my insurance, but did increase my daughter's policy on which I was a named driver, but as that was just a left-over from when she was learning, she just deleted me from her insurance. Had I just had the notice of a fine in the first place, I would have just paid it straight away.

Where I have heard of someone getting off was from the first notice being sent in ordinary post - they have 14 days to notify you - she did nothing until they sent her a recorded delivery notice of gong to court. In court, she told them she hadn't had the initial notice - they said they had sent it out in time - her reply was, "can you prove it?" - case was dismissed - I think you need a steady nerve to take such action though.

Idiot apprentice who has only had his licence for 5 months, was doing an indicated 120 on the M25 a few days ago in the early hours, he saw a flash of light behind him as he went under one of the gantries, he is awaiting something in the post.

If the camera was operating, he'll get a massive fine, instant ban, lose his job, will have to re-take his test, he has just strapped himself up for 60m finance on his car and his insurance once the ban is over will be horrendous.

Mistakes like that rarely go without a complete monstering. Having read the article talking about some people being massively over the ban total and getting away with it the backlash is coming.
