You get to keep all your wheels on the ground too.

The Tripendo separated its tilt and steering mechanisms, with one
stick controlling each of them. I don't have any understanding of
whether they were easy to learn, but they didn't _look_ easy.

Trikes have intrinsic advantages over bikes with regard to their
potential to carry heavy or bulky cargo, and their ability to cope
with slippery surfaces. I imagine that even leaning trikes maintain
these advantages over bikes to some degree, while having major ride
quality benefits over non-leaning trikes. So they're not useless, at
least in principle-- but it's tough to justify the cost of exercising
those advantages.

Local owner I spoke to said it wasn't more than a week before he
steered/tilted without thinking about it.

A parking lot with cones could be fun too.

Sure looks like fun on that sweet go-kart track with all the tight
bends. I wonder if it is as much fun out in the world where high-G
turns aren't as common.

Good point. Probably is a snooze on the average road, but it looks like it
could start a new olympic sport on special tracks.

It's reminiscent of the late, perhaps even great German Tripendo
trike:

Nice. I'd never heard of that one. It doesn't even have a video on youtube.
You can get plans for the Jetrike here.

And then there's the internal combustion version called "The Carver". Quite
a bit different really. I think BMW is going to start selling them in the US
soon.

The problem with designing leaning trikes is that they lose any chance
of positive steering stability if the steering is mechanically linked to
the leaning mechanism.
The particular problem is bump-steer.
The Trailmate trike is the classic example of a lean-steer trike that
seems perfectly fine at low speeds, but is unsafe at high speeds.
A lot of people have tried building these and learned (crashed) the hard
way they don't work so great at high speeds.
A lot of people (uninformed or ignorant) continue to try to build them,
tweaking angles and ratios and whatever, thinking they can "fix" the
instability, and they can't.
Another observed problem with these trikes is that the trike's seat
cannot sit vertically when traveling across uneven terrain, such as
riding along a highly-crowned road. Tilting the wheels at all results in
steering input.

The Vandenbrink Carver is one tilting-trike vehicle that IS designed
properly: the steering is conventional front-wheel, and the leaning
mechanism is mechanically separate (and electronically controlled, so
it's automatic).
-------------------
Leaning trikes are rather useless, at least as far as bicycling is
concerned. It doesn't make sense to go to great expense to built a trike
that can corner well, when (during bicycling) most of the time you are
riding in what are essentially straight, or very-nearly straight lines.
