So what happens if you are riding at a good speed, and you hit a pothole or other obstacle that bends a wheel? That could make it so the carriage cannot rotate freely inside the wheel, leading to rapid rotation of the passenger. I would not expect a good outcome after that.
I think that is likely the downfall of this kind of vehicle. Yes, with slosh control you can make it work well in normal circumstances, comparable to other vehicles. The failure modes, though, lead to worse accidents than other vehicles, and I don't see any advantages of it in normal circumstances to counter that.
