Too many unknowns with the mileage solution. The most obvious for me is travelling abroad - travelling by car between EU countries is not uncommon. Another issue is that the mileage of the car is not very hard to modify. In Eastern Europe, buying a second-hand 10 year old car, imported from Germany, is almost funny because most seem to be around 90-100 000 miles (140-160 000 km), while looking for the same make and model in a German auto website will show most cars have double the mileage.

A solution has been long in place in the US for commercial vehicles. It's called IFTA. It's possible because commercial vehicles have to report their mileages to authorities frequently anyway.

Can I cheat IFTA?
