I'm sure it will be all sorted to everyone's satisfaction and in the meantime MMC will have to deal with a local red face and probably change their testing drive routines
Why should the factory change their test drive routines? There's no suggestion that the test driver was breaking any speed limit.
.
It wasn't a comment about speed at all, it was a comment about the report that implied the driver knew there was something wrong so turned into that road off the main test route. If I were MMC I would find out what went wrong, have a pretest inspection on that particular issue and make sure that if a driver senses something wrong that the car is immediately stopped for recovery
In my business I work on a system that if it's gone wrong once, it can happen again however unlikely so you try to mitigate it by putting a system in to not let it happen again
