Really?
On a 4 cycle engine a specific valve will open/close once in every two engine revolutions. If the engine is spinning at 3600 RPM the valve will open/close 1,800 times a MINUTE.
What about a steam engine?
My 64 was originally a 283, another damn good engine, like most Chevys of the era. A previous owner had it bored out making it a 327, like a 350 with a slightly shorter stroke. Whoever rebuilt the engine knew what they were doing. 250k and still runs good.
Couldn’t have described it better!

Teslas have motors.
Real cars have engines.
With the materials available, the manufacturing expertise and machine tools, plus testing of parts and final assembly, there’s no excuse for a poor mechanical product.
I doubt it's the metallurgy, engineering or tooling. I strongly suspect the modern engine oils. According to an old pro engine builder; most oils used to contain Zinc Phosphate, but that has been "deleted" (probably tree huggers at the EPA)
You can still buy the additive at parts stores.
