We already have laws that forbid and punish for tampering with the odometer. People who tamper with the odometer and change the mileage should be held accountable according to both the odemeter laws and tax evasion laws. We would corporately spend less money doing this than we would spend on a "second" sensor that tracks the same metric, but is "untamperable." Additionally, this would be a good way to spread the money. The county that collects the tax on behalf of the feds could keep a percentage of the money collected for doing the work and then forward the rest to the feds.
