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)
Looking at models doesn't shed too much light, because some categories have their sales more concentrated across a few models than others. The post I was responding to used "The number of light trucks sold in September 2019 is almost three times the number of 'passenger cars'."
For Australia the same figure was 2.4 times ( https://www.caradvice.com.au/797477/vfacts-september-2019/ ) and 2.1 times in August - though this is only a recent change in the Australian market (passenger car sales being down considerably in 2019 versus 2018).
But yeah, the difference isn't as much as I thought it was, primarily because I didn't realise until looking into it now that crossover SUVs like RAV4s and CX-5s are considered 'light trucks' in those US figures.
