The mileage counters are already installed and you usually have to report what they say when you buy or sell a vehicle. If you disable said device, or otherwise tamper with it, you are losing a lot of useful data, especially if you have a new vehicle and you want to have warranty repairs done. You are also breaking state and federal laws.
If there are mechanical problems with the device, there will probably be some way of handling them, like assuming that you travel X thousand miles a year, based on state and national averages. If you don't fix it after a year, that number may be boosted. Eventually it will be cheaper to get it fixed.
The only 'problem' with the mileage meters is that they don't provide time and location data. But that isn't really a problem if you value your privacy.
That device has been around for decades, though not that many years ago it couldn't record more than 99,999.9 miles.
Using that mileage recording device, aka the odometer, would be quite practical. And there wouldn't need to be that much additional bureaucracy to do it. You could get rid of the gas tax bureaucracy while you are creating a small increase in the licensing bureaucracy.
