I mean - how are you defining most?

Most countries are quite poor and/or have small populations and aren't buying many vehicles period.

About ~45% of countries have smaller populations than Norway, and Norway is in the top ~25% of countries by size of the auto market...

Most countries are not the China and India, yet they make up almost 45% of the global population.

The US and China make up about 45% of the auto market...

There's a lot of European, Asian, and Latin American countries that have more in common with Norway than they do with the US or China or India.

Ok, we'll replace 'most' with 'all except for Norway'.
