Not to pile on, but the linked article you presented backs their data on New AutoMotive’s Global Electric Vehicle Tracker, a UK based group fostering EV adoption.

NAGEVT site only shows data for UK, is unclear which data sources they used, and whether they added PHEV (still ICEs) into the mix.

Don’t mean to come obnoxious, I just spent a few weeks researching the topic for 10 countries and my data differs a lot from theirs.
