1113430 2010-06-25 05:07:00 Now here's the bugger of a question related to that other thread.

Say Japs do read a higher speed than actual, the odometers would also read higher than actual. So for all the poor buggers with diesels (myself included), we're paying more than we should!
Interesting though ain't it?

Two edged sword that because it means your also more efficant on fuel burn :waughh:

Surely you have been guilty of "accidental" speeding right?


So you can accurately gauge speed to within 1km/h based on...?
Not everyone has speed calibrated super vision. We are human (for the most part).

Ironic with over 20 years of driving the same modern technology thats rapping our wallets is also the same technology that has made me question everthing I was taught about driving of being within 5kph of the speedlimt and maintaining the flow of traffic. Now I find out I was wrong!

The odometer is basically just counting. That is easier to do than convert revolutions of the cable or pulses to an analog display.

Do many cars have a digital readout of speed?

Two cars same model and I got a 2km per litre fuel differance because of an odometer error. BUt if I was to drive at half the speed of what I normally drive that error would not exist :waughh:

Most of them are in the upper reaches of the market though and european.

But if the speedo is inaccurace you could assume that the odo too would be innacurate, right?
In which case all of us paying RUCs are being ripped off.

Some do, some Mazdas (def RX8, possibly M3 or M6), post 2002 Altezzas and Windoms?, I know Hondas S2000s, so do newer civics (not sure if it's all models). Late model BMWs, Audis too.

Almost all sport bikes do though.

Husbands ute is out, we measured it on one of those mileage things on the road. His speedo is out too. And yes he mentions how he is ripped off everytime we buy RUCs. LOL.

Yes. I have been ticketed for speeding and that teaches me not to do it anymore.

I can't really afford it and it gets me nowhere anyway.
