This doesn't explain similar phenomena, though, like the Japanese replacing their cars frequently: https://www.nytimes.com/1993/09/12/world/why-the-cars-in-jap... https://www.picknbuy24.com/column_146.html It makes me wonder if a deeper cultural factor is at work here.

Japanese replace their cars frequently because taxes are structured so that after a few years it becomes worthwhile to buy a new car.

Yes, I agree that this is the factual reason why. But doesn't it seem odd that these are coincidental? I think it might not be a coincidence.
