Yeah, I like your continuation of my analogy. However, as I understand it, from someone I know who worked in the automotive sector a while back, all vehicles have a special emissions test mode. It exists for legitimate reasons such as you don&#x27;t want to have ABS turned on when on a dyno for safety reasons. It probably also exists for less legitimate reasons arising out of the history of testing practice -- essentially that the test never has been truly representative of real road conditions, and everyone involved in the testing process knew this. That being the case, all you need then is to add one more flag to the list of &quot;things to enable&#x2F;disable under test conditions&quot;. I agree that somewhere there must be some kind of record of when and who made that configuration change though.
