An engineer pointed out that due to the spreading of readings on various speedometers un-necessary take-overs where performed by those having a higher speed for the same reading than those having a lower speed for the same reading. Thus, the precaution is to some degree compromised by the lack of consistency in the degraded reading. This is further compromised by people knowing their speedometers is degraded, so they form their own rules of how to interprent them in a favorable fashion. The tires and air pressure in them comes in as things compromising the scale. My speedometer gives different readings on my summer-tires than my winter tires. I think I actually prefer more exact speedometer in all cars. Then there is less room for subjective judgements and less of a discussion altogether. I think we already did some work in a similar fields like weigth, lengths and time... I learned alot of what my speedometer told me when looking at my TomTom reading.
