Sorry? Cars are checked regularly (at least every two years for example in Germany) where any tampering can be detected and either reversed or further registration for the car refused. This system is already in place and the process of checking brakes, the engine, lights etc only needs to be amended by a process to check this system. I don’t see how this requires substantial "further steps".
