Faulty Speedometers & the law

[HoldenOnn]

A speedometer is a mechanical device and is basically a "gauge" of what speed you are indicated to be doing. It is not a precise instrument that can be classed as displaying something regarded as "fact".

The ADR regulations relating to speedometer tolerances basically back this up. Because something that has such a high tolerance allowable as 10% variance, should not be conceived as being 100% factual.

What the margin is now? One can only guess it's much lower!
I'll stop my rant now!

In SA the margin was cut from 10% back to 5% last year.
