Other groups have stated the same thing [1]. The car already has to detect dyno testing to turn off traction control and other things that are dangerous under these conditions, adding a flag to tweak the mixture the car works with under speed isn't so difficult after that. Trying to detect a pattern would lead to much more complicated logic, especially if you get a tester who decides to do things in a different order.
