Actually, aerodynamic drag is a significant factor on a Catrike. I do

I’d assume you’d still offer less to the wind than on a two wheeler?
Assumptions are as ever sometimes just plain wrong!

I'd be slightly curious to see drag data. A recumbent tricyclist may
have less frontal area, as precisely measured in square inches from a
front view photo. OTOH, such a bike+rider seems aerodynamically far
"dirtier" than a normal road bike. Two wide-spaced wheels with rims and
spokes churning the air, lots of transverse frame components with
non-aero cross sections, and especially two legs and feet cranking and
churning away in the very front of the bike. ISTM aero flow would be
completely turbulent from the first bit all the way back.

We could ask the trike guy for coasting and weight data. But that would
require a hill and his cooperation. Neither are available in his case.

Actually, the hills are available, but, indeed, I have no interest in
pursuing such data. It serves no practical purpose. Much like the
ongoing discussion (silly talk) of speed/power/etc changes while
cornering on a bicycle.

I've briefly ridden part of one ride with a guy who rides a recumbent
trike with motor assist. I suppose I could have tried drafting him to
see if I could assess the size of his wake; but he was far too slow to
ride with for long.

<LOL> Krygowski says he rides faster than the motorbiker.

For what it's worth, I've been told by people on two-wheelers who
tried drafting me that it's a lost clause. That was only their
opinion, and I don't know about someone on a trike drafting me.

On the other hand, I learned how to ride a two wheeler before I was in
grade school, with no instruction. I think it's totally ridiculous
that some fools would actually pay some dufus to teach them how to
ride...

Kinda depends on what your doing...

Indeed! Nobody has ever claimed that riding back and forth on a dead
flat, empty paved rail-trail requires any knowledge or skill. That's all
the trike guy does.

Only fools believe that any ordinary bicycling requires knowledge and
skill beyond what most twelve year olds pick up all by themselves.

If I do want instruction on something, give me a book and get out of
my way. Much like most classroom instruction, the instructors'
narrative often interferes with the learning process.

When I mention riding to actually get somewhere practical, he snarls
something like "I never want to do that, and neither should anyone
else."

Oh contraire, I don't disparage riding a bike to work or to the
grocery store, it's just that, nowdays, I have no need nor preference
to do it. Of course, in times when it made sense for me to do it, I
did.

Riding in the real world is one of the thousands of things he
doesn't like.

The world I ride in is quite real, but, indeed, like most everyone
else, there are many things I don't like.  Paying attention to a
buffoon who claims to have "superior" knowledge on simple things like
riding a bicycle is one of them. Following the rules, instructions,
and/or commands from some self proclaimed bicycle ride group leader is
another. Joining a club, buying and wearing a club shirt or jacket
with a stupid logo on it is another.

Earlier this year I came across what I assumed to be <LOL> a bicycling
class out on my ride.  A group of ten or twelve nincompoops standing
around, watching and listening to a geeking looking guy with a video
camera attached to his helmet.

Some people will buy onto any nonsense. Such things remind me of TV
commercials where actors take some magic pill and are then displayed
talking and laughing with a bunch of other actors. I can't even
imagine what goes through the empty minds of other people who view
that tripe. Probably the same kinds of thoughts that went through the
empty minds if people I saw in college level lectures frantically
taking notes.  Probably the same kinds of thoughts that go through the
empty minds of people who pay attention to political speeches.

Only in America.

J just think. All over the world people are getting on bicycles and
riding them with out the benefit of Frank's "can't ride with out one"
books. I can't speak for all countries but here in Thailand  the
vehicles with the lowest accident rate are commercial trucks and
bicycles,
