Speedometer calibration ?

FWIW, mine was out by 10%. I've gained 5% of it back by changing to larger wheels and tyres and I'll get the other 5% next time I buy new tyres because I'll buy a larger profile again (since I now know there is room). Read about it here if you wish:

Correction of speedometer through change of rolling ratio

Thanks, I actually saw that mentioned earlier. Tires are good now, so I'll suffer, but when I change them I will move to 17".

I have a 2015 Leaf S, so no navigation computer or GPS. The odometer is pretty accurate, reading about 2% high based on the mileage markers on the highways. However, the speedometer reads 7% high at any speed based on the timing between mileage markers and also the now ubiquitous radar signs that tell you how fast you are going. My other car, a Kia Niro EV, is accurate within 1%. Does anyone have a hack for correcting the speedometer, other than larger diameter tires, possibly through Leaf Spy Pro?

No.
