This illustrates the entire history and corporate mindset of GM.
My best friend (from age five)is now a senior engineer at GM. I do not want some lib lurker to find a way to identify him so I'll leave out specifics but he has told me stories that make your head explode.
When the engineers were developing new engines and new lines of vehicles the bean counters with MBAs stepped in and insisted on cutting critical corners that turned excellent products into mediocre failures.
For decades I watched GM introduce what should have been great cars that were pieces of half made rolling stock. These vehicles would be modified over the years until a nice car was finally produced but then the bean counters would cancel the line. Some of them even told my friend they forced the engineers to deliberately make a crappy product that people would still buy then promise to make the wanted changes through several years so those same people would come back and buy more cars. A really cynical ploy and a bad way to run a business. Bankruptcy was inevitable.
A few years after I bought my 1996 Chevy Suburban, the paint on the windshield wipers began to flake off. I asked around and found out that GM purposely painted the wipers that way so that subconsciously I would think, "My car is falling apart, I need to buy a new one."
