HN users are not representative. Kei car enthusiasts are not representative. Americans love F-150s, Tacomas, Highlanders, 4runners, RAV4s, CRVs, etc. They by-and-large buy the largest car/truck they can afford. You look up the sales numbers for this stuff and there's just no contest; e.g., CRVs outsold Fits by almost a factor of 10.

This is true, but even outside the US in a lot of Asian places with no apparent space for big cars everything is getting bigger, why is that?
