Not sure about the $1million or $10million (you have seven zeroes after the 1, that gets you to $10million) gold plated bikes. But Trek and Specialized, two main stream sold everywhere bike brands have bikes a LOT higher than a mere $6,000. Specialized SL7 is $13k. Trek Madone SLR9 is $12.5k. The mid priced bikes from these two companies are more than $6k.

to flat pedals. Now he cannot keep up on any climbs. And people with
training can get out of pedals just as fast as he can step off of a flat
pedal since they are ready to clip out when the conditions warrant care.

Can’t say I have found any performance difference at all, I used clipless
for a few years on my first road bike, was fine, never struggled to clip in
or out or had a clip less moment but I never loved them.

Few years back bought a CX bike for hacking about the woods plus road and
put some MTB flats on, and used my MTB flat shoes, ie pedals with pins in,
plus shoes with soft tacky tread.

In short with proper flats you can’t slide the shoe but have to lift to
reposition, unlike the road flats which are frankly terrifying slippy.

I’ve done 100+ miles on them, climbed up big mountains, tackled seriously
steep climbs etc.

I’ve seen opinions dressed as science with huge gains for clipless but
proper stuff the gains is marginal, apparently. Which certainly echoes my
experience.

Interesting the pulling up, gain is very difficult to prove.

Yesterday, when the pedal stripped out of the crank, I pedaled a mile with on leg. Try that with flat pedals.
Wow. How did the pedal strip out of the crank?
I was just riding along and the pedal started rocking. I immediately turned around to see if I could make it back but 10 miles from home the pedal, threads and all simply pulled right out. Pedals, as you know, are "British threaded" so you only have to tighten them to "snug" so I tighten them in with an Allen Key to keep from overtightening them and pulling threads. I stopped using the large and heavy pedals wrench long ago except to pull a pedal off. But this is the first time I can remember a pedal stripping out of a crank. The only cause I can think of is that the thread diameter on the pedal was undersize and the top of the threads on the pedal were cut flat on top.
Or you under-tightened the pedal, which is the most probable explanation. It's 30-40nm torque -- which is more than "snug," which is IMO about 12-15nm like Shimano crank bolts.
Jay, pedals are English threaded and under force they tighten. I took these pedals and cranks on two hard climbing rides so if they weren't tight enough before they were tight enough after.

I have never had any problems with FSA cranks and Look pedals. Looking at the threads on the Rock Bros Keo substitute you can see that the threads are not badly made but I'm willing to admit that rather than the pedal it might just as well have been the material of the crank. I just measured the threaded area OD on the Rock Bros pedals and it is pretty regular 0.55" which is .0125 smaller than the 9/16 but it is the same measurement as Look pedals measured in the same manner.

Did you tighten the pedals to recommended torque? If not, it backed out because the pedals were under-torqued. If so, then you have bearing binding. The question now is if you have ruined the pedal threads and need to replace the crank.

--Jay Beattie.

You remind me of a fond bike-wrenching memory:

In college I worked a few stints at a local shop, mostly assembling new
bikes for the Christmas rush (a thing that used to happen in the bike
biz, but does no longer, I'm told).

One day a Prof from my school came in with his three-speed, maybe a
Raleigh. I recognized him, though he didn't know me. His sadness was
palpable as he held a detached pedal in his hand. "I think I broke it,
is there anything you can do? Can it be repaired?"

The steel crank threads were rough, maybe damaged by the pedal coming
out, so you couldn't screw the pedal back in by hand.

I ran a pedal tap through the crank arm, probably in from the back side;
put a bit of oil on the pedal threads, in it went, and I tightened it
thoroughly. I'm sure I checked that it was spinning freely.

You would have thought I had parted the Red Sea. He was so delighted,
and he made me feel like a wizard. I don't know what the boss charged
him - I was just a temp wrench and prices were above my pay grade - but
he came back after paying and stuffed a five dollar bill in my shirt
pocket, which was a fair bit of money back then.

This is what BioNTec were working on until Jan 2020.
In the last 15 months, they have been given billions to ensure mRNA

Id' say once we have spare production capacities for mRNA mecidation,
individually tuned cancer vaccination will not be that far off any more.

In theory but the usual pedal thread repair is a 5/8" full

Not the best, not very strong, quite cheap, and doesn't require tools
to fold down. More of the same:
https://www.google.com/search?q=folding+bicycle+pedals&tbm=isch
There are also removable pedals:
https://www.google.com/search?q=removable+bicycle+pedals&tbm=isch
For example:

Perhaps I'll consider those if the current system ever gives me
problems. But I've had no problems so far.

screwed down by hand. I tracked the guy down and gave him a lesson on
quick release levers. He was very grateful.

I found him in his office in the English department.
