    Just to repeat my previous post:
    "Actually, it is because Manufacturer's don't want the liability if the speedo should read LESS than the actual speed, and you get a speeding ticket. It typically will read about 2-3 mph high."

    To add to that, I believe there is a "United Nations" agreement that specifies this discrepancy.

    Actual speed being 2MPH lower than the speedometer reading is what I'm seeing as well.

    Yes, but nearly all the signatories to that particular UN standard (the one linked from PriusChat multiple times in the past decade) are EU and Asia-Pacific countries. None are in the North/Central/South Americas region.

    How much hand-wringing can we do over this? If you're adamant to do the actual limit: "speed" by 2 mph, done?

    For me, it’s a question of accuracy.

    “Sir, do you know how fast you were traveling?”
    “I think so, Officer. You see, the speedometer said I was driving 67, which - according to the United Nations - actually means I was driving 65.”
    “Step out of the vehicle, sir.”

    On Toyos the speed was 1 mph low according to Waze and Garmin... temporarily on Hankook 737 and now the speedometer is 2 mph low... switching to Bridgestone next week...
