Im OK with analog speedometers being optimistic, but ever since I installed my first bicycle computer on a motorcycle more than 25 years ago, my brain can only accept a speed displayed as a number as the true speed within the margin of error achievable by the calibration technique.
I calibrated the bicycle computer to be accurate within +/- 2.5 meters on 1000 meters, by using T-shaped marks on the highway exactly 1000 meters apart, which were there for the highway police to calibrate their equipment.
My current scooter has a speedometer with 2" tall digits and like all Suzuki's it was 10% optimistic, before the SpeedoHealer. Now it never differs more than 1 kph from my GPS.
It's such a pleasure to be able to be speeding exactly 3 kph below the threshold for speeding tickets, without doing math on the fly.
If it has a digital speedo, corect it.
If it has a mechanical speedo, get a digital device which tells you the true speed.
