looks like the raw accelerometer value is also drifting in the beginning in this drive. Likely due to device heat-up.
@fredyshox Can look into it, but would probably need to temperature calibrate to fix this. This is a very different problem than greg's post
In this route, I got it to converge to 2.1 degrees (in ~10 seconds) in the same spot as above, when I started the route it reported 0.75 degree here. https://connect.comma.ai/57048cfce01d9625/00000310--6f8d1bfc12
