This reminds me; even if one buys brand new car, the car's odometer isn't 0 either. Usually ~20km or so. (Driving it out of factory, driving it onto truck, off the truck, onto the ship, off the ship, onto the truck again, at dealership, off the tuck again and in dealership, into showroom or parking spot + some from test drives from potential buyers.)Obviously the drive was tested at the end of manufacturing cycle.
Why would manufacturer need to hide that by wiping smart values?
It was used for less than an hour. It's new.
