Of course the box doesn't give you yaw angle, it gives you yaw rate. I agree about being out of the realm of most drivers, including myself.

yaw and pitch are just derivatives of this hardware, which is far more accurate than the gps calculations.

I am wondering how you use that data to your advantage?
Keep in mind, it gives you yaw-rate, pitch-rate, and roll-rate. You have to accurately take the integral of each of those to give to the instantaneous yaw, pitch, and roll. Let's assume the software does that integration for you (accurately?) then I am still not sure what you do with the pitch and roll. Honestly, I am not even sure what you would do with the yaw except maybe look at the overall slip angle of the car to see where you are getting the most grip (Gs?). Even then, you are missing a large piece of the puzzle without steering angle. All that aside, let's says you have accurately obtained velocity (including direction), yaw angle, and steering angle. What would you do with that information?
I am less concerned with getting information and more concerned about what is within the realm of my ability to analyze AND apply that information to my driving to improve. In the end, I can get as much data as I am willing to pay for but I'd like to avoid paying for more data than I can use.
