I jest ... of course.

Doesnt the speedometer over reporting speed mean that fuel economy is worse than the MID is showing us? i use tires that are 4.9% larger in diameter than OEM. They are also 4.9% more circumference. Comparing my speedometer to phone mapping apps it is now accurate with these tires on the vehicle.
miles traveled divided by gallons of gas used
If larger tires make my odometer reading off, my mpg calculations reading will be off, too.
I wouldn't know how to calculate my mpg using a speedometer reading?
I don't understand the logic of countries mandating speedometer readings being off. Seems stupid to me! Do countries mandate odometers readings?

Some ghostdrivers don't believe in universally valid international agreements and regulations and think they have the liberty to write their own opposing "standards".
Which comes first, the odometer or the speedometer? Depends on the instrument principle.
Strictly mechanical: chronometric as in the Smiths of England samples every 5 seconds (or so) the distance travelled and shows this as speed while the odometer registers the distance by gearing.
Electro-mechanical: distance by gearing while speed is a magnetic rotational force opposed by a spring on the needle shaft. Standard in USA until the advent of the computer.
Electronic: sensors count pulses on tone ring attached to either a wheel, ring gear or transmission output shaft for didtance while computer integrates pulses vs time to step motor speedo. Minimal mechanical (tone ring), major electronic.
