The cheatware detects when a motor undergoes emissions testing, and then

how is that possible?

One report said that it detected the steering wasn't being used when the
car was being "driven" on a rolling road test rig to check emissions.

I have seen a suggestion that there's a "test" mode that on the surface
disables ESP etc for rolling road testing, but I've never seen any
evidence of this beyond hearsay. Even if there isn't, if it's a 2WD car,
pretty easy to tell if it is on a rolling road via the ABS sensors, and
even if 4WD, as has been suggested elsewhere in this thread, via the
steering angle sensor.
