Ive done over 12,000 miles now on all the local trips the mileage has tallied up, anything further or unfamiliar I haven’t really looked at but nothings setting alarm bells off. I wonder if the car one is generated from the abs reluctor rings and the other is GPS data as to how that explains a discrepancy I dunno.
That’s the trouble with software driven digital displays how honest are they, just like lcd panel fruit machines
