It makes technically no sense if you can harmonize the regular driving condition into one single realistic cycle. Then the results are reproducible and comparable.
OEMs all have their in-house driving cycle to better reflect the reality[1] than the boring standard cycles.
The emission/consumption performance for some given customers is easily predictable.
To prevent cheating, you'll just have to open source the software inside.

My assertion is that you can't do that with a single realistic cycle precisely because there is a single one. Overfitting will occur, an ensemble of actors can't be gamed.
