True but he would be a mobile road block that would incite (sp?) motorists travelling at an accurate speed to par take in more dangerous driving style to pass the obstruction.	coldfront (15814)

Speeding, sure, but not everything in life revolves around it. I'm more concerned about RUC charges. 49$ per 1000km. That ain't cheap. If the odo is off by say 10% that's quite a big difference. I have driven nearly 20k km this year. If my odo is off then I'm paying too much or too little. This is not cool. Can we please leave speeding to the other thread and let's stick to RUCs on this one, OK?	Cato (6936)

Has he checked that the Tyres are the correct size for the vehicle? First thing worth checking.	coldfront (15814)
1113444	2010-06-25 07:02:00	Most of them are in the upper reaches of the market though and european. Most cars made in the last 15 years or so have a digital speed reading feeding into the ECU, which you can attach a monitor to through the OBD port. This would probably read exactly the same as the analog reading though. Things like tyre pressure and wear can affect the speed readout because the alter the diameter of the wheel, so it's damn near impossible to be perfectly accurate.	ryanjames.powell (13554)

OK. But if I was driving a truck and trailer and the max legal speed is 90Kmh how do you get past me?	Sweep (90)
1113446	2010-06-25 08:14:00	OK. But if I was driving a truck and trailer and the max legal speed is 90Kmh how do you get past me? Easy because you are more likely to be a considerate motorist who will pull to the side of the road when they can ;) How you know if your doing 90kmh then? Trucks more accurate you reckon? Cancels itself out really. Think about it!;)	coldfront (15814)
1113447	2010-06-25 08:33:00	Sigh. And what about the truck going downhill with exhaust brakes on? And let's say approximately 90 Kmh. And let's say people sit behind until it is safe to pass which they should do. You seem to be nitpicking over 1 kmh.	Sweep (90)
1113448	2010-06-25 11:15:00	Another occasion driving in convoy with another car of identical specs driven by my other half I put down here slower speed to being over cautious. We swaped cars and she ended up pulling away from me at 100kph.:eek: No differance between them with GPS and Dyno road check discovered a 9kph differance in speed at100kph registered! One up 3 kph the other up 6kph the ironic thing though is both at 50kph were spot on doing 50kph. What do you mean "no difference between them with GPS"? In your other post one was down 3 kph. Why not mention model?	PaulD (232)
1113449	2010-06-25 11:45:00	What do you mean "no difference between them with GPS"? In your other post one was down 3 kph . Why not mention model? Does it matter the model? Not really just matter that there was a reading differance of 9kph between them . The GPS and Dyno just confirmed which was where on the speedo compared to actual .	coldfront (15814)
