It may not be perfect and if I get my face close enough I can see the pixels, but that doesn't make it not correct. The text is displayed, I can read the letters without issues - that means they're displayed correctly.
I'm using a different hidpi display as well, and don't really care for the difference. The link does discuss real issues, but does not prove anything about "text displayed correctly".
1080p on a 14 inch laptop is the same density as 4k on my 28 inch screen. I have to try really hard to see any imperfections. Under real-world conditions suboptimal lighting & reflections are a bigger issue on a laptop screen than some sub-pixel features of text.
I like your reasoning here but lol at your specific examples. Nobody really considers Lambos or Jeeps as being particularly drivable. Lambos try to kill you and Jeeps rattle your brain.
The blog post is good in showing that the "non-starter" because cannot "display text correctly" doesn't hold. Specifically it talks about how Macbooks by default utilize fractional scaling that messes up pixel-crisp text. Gonna bet that there's a significant overlap between those that call for ridiculously for their size high res displays yet are fine with those defaults.
