Seems like the gyroscopes would help with a bunch of those — traction issues become less about keeping the bike upright and more about controlling where the bike goes.

I don't see anything about ABS in the FAQ, but that would avoid the problems of locked front or rear wheels.

Also, I imagine this has only one brake control, unlike a motorcycle, so you can't lock up one wheel by stomping on your rear brake but not grabbing the front brake.

I also wonder how effective the gyroscopes would be against a high-side crash. Would the having to adjust for hills limit their ability to prevent one?

Having a seatbelt seems like it might help with high-sides, too.
