I have read that the speedometer is 5% off so that will mess up your numbers if not accounted for.

I wonder if that’s true. Is it OK for manufacturers to do that? Bjorn Nyland said the speedo in the Kona EV he tested was off. I know that in Japan at least they have to be very precise. A speedometer test is part of ‘shaken’ car inspections. If your car doesn’t pass the test you can’t register the vehicle.

In the U.S. at least, there's a tolerance for speedos, and knowing that erring on the high side won't get them or their customers in trouble (and tends to make the latter a lot happier than an error the other way) manufacturers always have their speedos read high. Most other countries have similar requirements for speedos to never read low: https://www.theglobeandmail.com/globe-drive/culture/commuting/why-you-may-not-be-driving-as-fast-as-you-think/article11487709/
