Given that mileage is already recorded at the time of roadworthiness tests, and that each individual can see this for their own vehicles on the e-government, I propose that another small step forward be taken:
A website should be set up where everyone can see the vehicle data on the basis of the vehicle's unique identification number (VIN / chassis number) (this really needs very little work, because you already have a database with the data).
Let the State show that it wants to put a bit of order in this area.
