It is visually outstanding. The only thing that sticks out to me is that the steering column bends out forwards towards the ground (negative trail), which would make it oversteer rather than self-stabilize. Interestingly there's a slight positive trail bend in the second one, though.

It’s really fascinating in a way because I would have thought that this would be one of the least difficult parts of the challenge.
