I am nearly 100% convinced that at the right speeds the device is simply given enough conflicting information and tries to over correct for one thing just slightly after the next that it is enough to throw the rider. My belief is that the LSF is actually the culprit here and that if the device was not getting the "back and forth" information provided from it the condition wouldn't exist.

This exact same curb cut would be trivial for a bicycle to negotiate.

If you'd like to test it out, I've included one that I now know can be a problem and it's a fairly repeatable test too!
Well, I can't open whatever file this is, so cannot see whatever area is being referred to. All I know is I keep my knees bent, keep the LSF aligned with my body, let the base move where the ground takes it, and all is well. Kind of like skiing, sort of. Have you ever been skiing quade?
