The EU is about 450 million people with above average disposable income for global levels.

I'm not sure if other countries are following, but they will :-)

Somewhat similar story in the US with California and New York pursuing 2035 sale bans - other states don't necessarily have to even follow, California has been the benchmark for US vehicle emissions standards for decades. The state has big car culture and a big population. Automakers often build things to the California standard and sell the CA-standard cars in the rest of the country. Its just not cost effective for them to make minor variations in the models.

Other countries are leading. The UK is 2030. Norway is 2025.
