I don't agree.
Typically the manufacturers set the speedometers
to read HIGHER than what you are actually going.
So if you think you're going 70, you're really going 67mph or so.
They probably do this for safety concerns.
I have calibrated (used LOTS of sample points) my '86 RX7 with the mile
markers on the highway and have found my speedo to read 2-3% higher
than actual.
My friends' results are also the same, so I have a two sample points
to back my observations.
Other viewpoints?
