Thread: What device/s can u use in/on your car to record your vehicle speed accurately?

The Equipment used by the police / Departement of Transport must be calibrated to some standard.
There must also be a standard that speedo equipment needs to be calibrated to, otherwise, there is a major disparity here, one rule for the police, nothing for us.

Find that standard / rule and then find equipment that is / can be calibrated and maintain calibration against that standard / rule.

Then install that equipment and maintain it. You will also need to set up a regular calibration by an appropriate approved facility to do so.

However that wont stop you speeding, only give you information to prove / disprove.

What I need is a limiter that wont let me go past the limit!
and last night a radar detector wouldn't have helped me, they got me as they were coming out of a round about on a curve.

Fairs Fair

Police radar will do it.

drive through a known speed camera zone above the speed limit noting your speed as you get the flash.

for a couple of hundred bucks they will send you a letter with a photo showing you your exact speed.
