At about 80 mph, the suspension went unstable and tended to toss
riders into ditches, and every once in a while the middle cylinder
would seize up, so you kept your hand on the clutch lever at all
times. I had to tear it down and hone it out twice before she totalled
it and lost her spleen. Good riddance [1].

Has anybody actually built one?
I've seen similar things with two rear wheels.
If you look carefully you'll see that the front axle is pivoted at it's
center, so the thing will ride like a motorcycle until you hit the tilt
limit on that pivot -- at that point I imagine that all hell will break
loose unless you have a _very_ skilled rider who can compensate for the
change in the effective pivot point while keeping the thing going.
