Earlier quoted context omitted.
Keep in mind that the best selling passenger vehicles are not called "car" in the US statistics, but "light trucks". The number of light trucks sold in September 2019 is almost three times the number of "passenger cars". https://www.marklines.com/en/statistics/flash_sales/salesfig...
That really reinforces the root comment's point about fashions in vehicle choice / driving what everyone else does being the 'safe option'. The countries most similar in culture and affluence to the US don't seem to buy those passenger utility vehicles and passenger cars in nearly the same proportions, so fashion looks like a big part of vehicle choice.
In Canada [1] -- looks like about 3 out of the top 10 models are "passenger cars".
In Australia [2] - it's the same thing. 3 out of 10 are passenger cars (and both have a top 2 being a pickup - although the .au spread isn't as wide as .ca)
