To me, requiring a special mode, is just inviting trouble, much like EPA (and Environment Canada) fuel efficiency testing protocols. Obviously, they have to have a testing procedure of some sort. But, this happens in all kinds of automotive scenarios, from racing all the way to the most generic production vehicles. You create a very specific test, engineers will strive to pass that test, period. Unfortunately, there can be unintended consequences and even cheating.
Look at all the complaints about EPA fuel economy testing. Cars are designed to provide good fuel economy numbers for EPA testing procedures, not necessarily for real world driving.
