Moreover, Detroit cars didn’t get worse but rather stagnated in comparison with Toyota/Deming’s continuous improvement model.
To be fair, that ‘81 VW camper in our driveway doesn’t fair much better. I’d rather rely on an ‘80s Chevy Citation to get me home than that piece of parts-bin shit. Part of the problem for a lot manufacturers were 70s-era emissions controls, which is a small part of why a 4000 lb. vehicle has an engine that put out 68bhp.
The well 20-something yuppies who got dragged around in their parent's well cared for 90s Japanese cars and look back fondly on those days.
The edge between manufacturers is very, very, small. 20+yr and 3+ owners later how a vehicle is treated will completely dominate who made it when it comes to how reliable it is going forward. 90s domestics definitely ignored the sedan and compact market a little, after all, minivans then SUVs were where they money was. They didn't innovate. But they gave their car platforms the same sets of tech and systems that the flagship SUVs got so they're no less reliable. The "hurr durr domestics are unreliable" tropes that HN loves comes from the fact that they're cheap (compare MSRPs of the day if you don't believe me). So people bought them with the intention of treating them as disposable. So then they don't hold their value, so then they get sold to people who can't afford to do maintenance. And the cycle continues.
I think a similar story happened to a lot of American families, and the stereotype grew.
The reason why Italian and German small businesses are so innovative is because the global market is hyper-competitive.
