I'd be more impressed if Stan managed to turn a corner on his
contraption.

Yeah, but what happens when you try to turn it?

We couldn't have been the only ones who did this -- at a small scale -- in high school in the '70s
.....

Moreover, a round wheel on a round planet gives a road and wheel of congruent shapes -- of have I
misunderstood the "brain-teaser"?

It kind of reminds me of Spider Robinson's (or was it Larry Niven?)
take on ice skating: a rink of upturned blades and you strap a couple
blocks of ice on your feet. Of course, you can only go in circles...
and heaven help you if you fall!

Larry Niven, in the short story "What use is a Chocolate Covered
Manhole" IIRC

Reminds me of growing up in a quiet residential neighborhood where it was
safe for us kids to ride bikes. My mother wanted to ride a bike also, but
couldn't ride a two-wheeler (poor coordination I suppose, but a great cook).
She asked my dad to buy her a three-wheeled bike, 3-foot basket in the rear.
Her first ride, we all stood out on the lawn as my mom took the bike around
the block. About 15 minutes passes, we start to worry, then we see her
hauling ass around the corner on two wheels, the third wheel at least a foot
in the air. Surprised she didn't tip over. Now, my parents live out of
state, and I asked my dad if mom still rides that thing, and he says, yea,
sometimes on two wheels.

That is *so* cool! Almost (but not quite) makes me want to stock 3-wheel
adult bikes. But the saner part of me says those things are way too heavy
to haul up the stairs to our repair & assembly area (workers comp specials,
we call such bikes).

Actually I thought you could get Trek to make them out of OCLV 110 Carbon,
throw on Bontrager Race X Lite wheels, change the name from Madone, to
Madame, and you got yourself one hell of a 3-wheeled bike. Bring a lot of
grandma's out of the woodworks.
p.s leave the teeth at home!
