Many jurisdictions require annual inspections. Those jurisdictions could require the inspection include reporting the odometer to the state.
Adding an odometer only inspection requirement to jurisdictions that don’t currently have an inspection wouldn’t be terribly onerous. You could make a device that plugs into ODBII and reads the odometer and VIN and reports it to the state, it would take less than a minute of labor per reading. Combine that with some policies that encourage oil and lube shops to get the device and provide the reading at no extra cost when you’re doing an oil change, and most people wouldn’t see any increased costs or inconvenience.
