No, actually I blame GM. The NHTSA does not require it to operate at all times and does not specifically say that there can't be something used to consider what the vehicle is doing.
As a matter of fact, if I remember correctly, the NHTSA allowed 2 types of pressure monitoring. One that actually measure the pressure itself and the other that measures harmonic frequency and/or uses wheel speed sensors from ABS or something along those lines. The second type would require it to operate only at a higher speed which is what should happen with off-road capable vehicles, at least.
So, good job sticking up for the employer, but GM knew this regulation was coming a long time ago and could have prepared better for it. Passing the buck won't cut it here. Just the same with DC/Jeep, Ford and the imports that are built for off-road.
Just so happens the H3 is the first that I have heard of that has the system and it seems to not accomodate.
