Odometer in Cars (FH6)

I would like to see an implementation where, when you buy a car and it is delivered with, for example, 0 miles, the mileage continuously increases as you drive and is permanently retained.

In other words, I buy a car → drive 30 miles with it → the car now shows 30 miles instead of 0 miles.

Currently in FH5, there is an odometer, but it does not work like in a real car. When I switch to another car and then return to the previous one, the odometer shows a new mileage each time.

I would like to know how many miles I have driven with each car.

Edit: km not excluded
