That should easily be challengeable in a court .. most cameras are set to 10mph over the limit to guarantee a conviction IMO anything less can be argued by a defence the that your speedo is not accurate enough to tell you exactly what speed you are doing as most cars arent , because the law does not require it to be calibrated like a tachograph in the police car ,or LGV, for example..... just my humble opinion or were you in an LGV ?

edit .. give you another example .. you fit larger tyres on your car than what it was built for .. your speedo will be out again

If your relying on Road Angel to be upto the minute accurate, stick to the speed limit to be on the safe side.. It also cannot detect mobile speed cameras when they get you from behind..

The new system updates to the device via GSM, updates are automatic every few seconds as you drive - so it should be moderately accurate I would have thought. I've used one and it was far better than the portable radar/laser detectors I have. Quite legal too.

I would add that the laser jammers will cause the Police to have a major sense of humour failure - you would need to be very careful fitting these.
