Yeah, not just ugly -- they were also unreliable and terrible to drive. I learned on some of those godawful machines. Fortunately, we also had a '65 Mustang kicking around the family, and I got to drive that sometimes.

This too. One of the most recalled vehicles in automotive history was the 1978-1980 (Third generation) Monte Carlo and its Pontiac, Buick and Oldsmobile clones. Only to be outdone by the Chevy Citation and Pontiac Phoenix in the recall category as well as horrible drivability and reliability. Is it any wonder GM's world market share dropped from over 50% to under 30% by the mid-1980's.

I don't think I've ever seen a carbon frame that stress cracked from use. I've seen a lot of steel bikes that have.
Most of the dead CF frames I've seen were either impacts, failures of small parts or galvanic corrosion where aluminum lugs or cable stops rotted out the bond.
I would expect a bike like a Calfee Luna to last essentially forever.

I HOPE you are not including the AMC Pacer and Hornet. Then there is Subaru Tribeca and Pontiac Aztec. Not to be confused with the AMC AMX.

And then there was the Gremlin which was basically a Hornet with the arse end chopped off.
AMC certainly had some badly designed cars that drove like cr@p. However, they were actually comparatively reliable (for 1970's American cars) and cheap and easy to repair when the did break.

Why not write directly to bike manufacturers who make CF bikes, like 3T for example and ask them for their data rather than internet speculation...

If you believe the entire world is in on a Big Bike conspiracy to make people buy dangerous frames and brakes, what would you expect 3T to say?

my nice bike is at home
Just changing the subject back to the original question :
My Trek 2300 from '92 or '93 (?) see's well over 1000 miles per year on NYC streets.
It also gets a ****-ton of lock-up time outside while I shop or eat & drink or look-it stuff inside.
I am not easy on this bike and neither is anyone else, it's held up.
Thankfully, my brother handed it off to me after he had completed Paris - Brest - Paris on it
(was also shipped in a suitcase there & back from VT then )
We have put it through the test for sure.
ps. a similar 2120 I know of had a not-catastrophic metal failure, the seat-post bolt area sheered off.
Probably the binder-bolt was too tight...or aluminum shell was too weak, we fixed it with two large washers.

I believe Koyote was referring specifically to American cars of the 1970's.

And then there was case with the Chevy Corvair which was the inspiration for Ralph Nader's "Unsafe at Any Speed". The engineers at GM said that the Corvair should have a front stabilizer bar to prevent oversteer and possible rollover. Here again, the bean counters at GM didn't want to spend the small cost to make the car safe.
nothing wrong with the Corvair, if you know how to drive. Porsche has been able to use that same rear engine, flat six air cooled engine to win multiple Lemans, Sebring, and Daytona victories.
Problem is when you put a rear engined car that tends to oversteer in the hands of poor drivers who do not have even an inkling into chassis dynamics and how to actually control a vehicle.

It wasn't the rear engine that made the Corvair unsafe. It was the rear swing axle suspension that caused the car to oversteer. And as I said, this problem could have been easily rectified with a front stabilizer bar. But the bean counters at GM decided that potential lawsuit payouts would be less than it would cost to add the stabilizer bar to the vehicles.
or people, could learn to drive. Oversteer is a good thing if you know what you’re doing.
”Oversteer” isn’t’t somethng bad, like the car steersmore than you want. If just means at the limit, the rear tends to come out, more than the front, as opposed to under steer, where the front washes out before the rear.
Every car at the limit will either under steer or oversteer. production cars tend to be balanced to under steer because they are easier to control, particularly by drivers with no concept of chassis dynamics.
oversteer is actually a good thing if you know how to use it. The 930 turbo I posted earlier was prone to significant oversteer, Yet it’s an amazing car in the hands of someone who knew how to drive it.
So, yes the Corvair could have been designed to be more idiot proof, but was by no means unsafe in the hands of a competent driver.
