Hopping mad not so much at being 'caught' but that I have no way of contradicting the so called evidence. I've never even been stopped by the police before.
I was apparently clocked at 43 (an indicated 45-46) in a 30

!!!. This was at the 'Crooked Billet' on the A30 just after the junction with the A308 heading east towards London (51 deg 26 min 11.48 sec N, 0 deg 29 min 55.59 sec W for Google map).
Just to set the scene. The A30 goes from a 2 lane DC 70 NSL to 30 mph just before the roundabout and stays at 30 mph for about a mile. If the traffic lights on the roundabout are green then the traffic slows down to about 40-50 for the second set and then slows down to about 35-40 when back in the two lane section. This roundabout has 4 lanes going through it so you get 2-4-2 lanes all within a few hundred yards.
This can make for some interesting situations so I always keep below 40 exiting the roundabout and slow to 30 shortly afterwards. I've traveled this bit several hundred times by now so know the problems.
Anyway I sent of for the photo as I genuinely didn't know who was driving at the time. Got the photo back and realised that I can't accurately work out where the car was when the snap was taken.

How do I find out where the snap was taken from. Will the 'safety' camera people tell me. The snap was apparently taken from 187.1m away at almost dead ahead from the car.
I just don't do an indicated 45 mph at the point where I think the photo was taken.

How am I supposed to defend myself (if it is neccessary) against a system that deems that a human plus a bit of machinery is always 100% correct under all circumstances. (I programmed big and complex IBM systems around the world for a living so have some experience of what can go wrong - TPF and ALCS/MVS for those that recognise them).
I had just taken delivery of the car the day before. It is a Toyota Yarris T3 M/M - hardly the fastest car in the world. My other one is a bit faster.

Can I say that I was just familiarising myself with the car (I was).
Realistically there is no way out of this because I'm trapped by the system. Its certainly not justice. Not sure about the legality either.
By the way it was a police car sitting at the roadside and a police logo on all the paperwork.
Any comments welcome.
Sharing a problem is supposed to help. It just puts up my blood pressure.
