Third speeding ticket in six months!!

[Acme Thunderer]

I'm in the fortunate postion of having a built-in speed limiter. When in urban areas or strange places it gets turned on. I don't care if there is a build up of traffic behind me.

Had a situation couple of years ago when doing 30 in a built up residential area at night, car behind me didn't like it so overtook me, I thought, then the next car overtook me and started wandering what everyones problem was. Then the 2nd car turned on its blue flashing lights and pulled over the first car.

So do u do 27mph on the speedo to allow for error?

I always do. So do the majority of motorists in the city where I live, and in all the other places I've driven. I think you have a nasty case of confirmation bias due to the need to justify your disregard for the law to yourself.

I'd say they will be averaging around 33 mph, perhaps a little less only due to speedometer inaccuracies that they would mostly be unaware of.

Well my situation has now made me think about sth similar, I don't mind the limits, for me it's the watching/gauging or just going at 25 to be sure that's the issue.

I'm now looking at ban insurance, road angel, radar detector, and now auto speed limiter....

All of them - do you know that for sure? Bristol cars were accurate all the way allegedly...

I always do.

So do I. As I am concerned about killing someone. But I have no issue with driving at 100mph on motorway in clear conditions with few cars.

Driven in London much? In central London it is obviously impossible to speed - but have you tried the suburbs?

When I first started driving people generally observed the speed limit. At some point I noticed people speeding more and more in London and then it spread outwards. Maybe we seem the same road conditions and notice different things?

Vehicle manufacturers calibrate speedos to over read so they aren't made liable for drivers getting speeding tickets.

Also when i lived in SW Scotland everyone did 80mph down the country lanes which tulip me up seriously and everyone drank and drove - pub was miles away. Coppers never bothered unless u were seriously driving like a tosser so where's the logic? I get done for 5 mph over on a wide suburban A road at 07:46 Sat morn with no cars for miles? That's my beef.

Link/ref/myth?

In many countries the legislated error in speedometer readings is ultimately governed by the United Nations Economic Commission for Europe (UNECE) Regulation 39[3] which covers those aspects of vehicle type approval which relate to speedometers. The main purpose of the UNECE regulations is to facilitate trade in motor vehicles by agreeing uniform type approval standards rather than requiring a vehicle model to undergo different approval processes in each country in which it is to be sold.
European Union member states must also grant type approval to vehicles meeting similar EU standards. The ones covering speedometers [4] [5][6] are similar to the UNECE regulation in that they specify that:
The indicated speed must never be less than the actual speed, i.e. it should not be possible to inadvertently speed because of an incorrect speedometer reading.
The indicated speed must not be more than 110 percent of the true speed plus 4 km/h at specified test speeds. For example, at 80 km/h, the indicated speed must be no more than 92 km/h.
