1113421	2010-06-25 04:14:00	Afaik, yes. Generally off the gearbox. Not sure on the brand new cars though, they are probably getting fancier.	wratterus (105)
1113422	2010-06-25 04:26:00	As stated above Cable operated speedometers/odometers run via cable from the Dashboard to a gearing set called the head which in turn runs off the gearbox. Inveriably the error is so slight you would not notice it unless travelling measured distances at a higher speed limit.	coldfront (15814)
1113423	2010-06-25 04:35:00	What I would like to know is what do people do with the time they think they save by travelling at 120 Kph as opposed to 100 Kph?	Sweep (90)
1113424	2010-06-25 04:39:00	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?	Cato (6936)

I don't think people speed to get anywhere faster. Hell if you are so worried about speeding that you look at the speedo ever 1 and a half seconds I bet you are more likely to crash than cruising at 120.	Cato (6936)

Inveriably the error is so slight you would not notice it unless travelling measured distances at a higher speed limit. and modern ones run off an electronic sender on the gearbox. some are adjustable, some are not.	tweak'e (69)

And I might add I use the rear view mirrors more than I check the speedometer. Microwaves, radar and speed cameras are not the only means of checking speed.	Sweep (90)
1113428	2010-06-25 04:54:00	So why do they speed then? Usually it's because they are not aware they are speeding. Surely you have been guilty of "accidental" speeding right? And I might add I use the rear view mirrors more than I check the speedometer. Microwaves, radar and speed cameras are not the only means of checking speed. 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).	Cato (6936)

Microwaves, radar and speed cameras are not the only means of checking speed. Because people trust that dial in front of them to be showing the true speed they are traveling. Valuable lesson I learned was driving a van to Wellington I was doing the 100kph yet people were passing me the assumption they were speeding! Wrong when I later checked it with a GPS I was doing 90kph and consistant out by 10kph in the speed range from 50 kph up. 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.	coldfront (15814)
