I've heard before that the odometer read actual distance travel of the speed sensor in the gearbox or whatever so will be accurate and the speedometer just rounds it up a small bit then for safety reasons. So the odometer does not read the distance traveled of the speedometer.

since its illegal for a speedometer to under-read , and since most of them are based on a mechanical clock spring being driven by a small motor, the margin for error is built in under the basis that the clock spring may wear a bit over time , at some point towards the clusters dying day it will probably end up bang on , but its merely a compensation for the analog nature of the speedometer and the odometer would have the accurate reading.

Ode is accurate.
Speedo is accurate but as tyres wear it over-reads.

Sorry but you are decades behind in your knowledge of technology. Clock springs haven't been used since possibly the 70's/80's!

Clock spring????? Maybe if you're talking about a 1959 Morris Minor.
'Analogue' speedo dials nowadays are driven by digital stepper motors, so no 'wear' possible.

The odometer is the one responsible for keeping track of the vehicle’s total distance driven throughout its entire lifetime. A speedometer keeps track of the speed at which a car is going at any given time. Finally, a trip meter is similar to an odometer but it only counts the distance of a trip and is resettable.
Hope this helps.. :)
Six years later, I doubt it matters, tbh...
This is the second ancient thread dug up today to copy and paste the same thing. Someone has a semi for odometer/speedometer threads.
