China was likely excluded because it was tied for 6th place at the time this graph was written (By the IEA percentages now, china is only at 53% while sweden is at 61% - it is a somewhat misleading statistic), and this is a list of the top 6 european. And as to the "the US doesn't have EVs" meme (sigh):

Retail sales of the battery-electric (BEV) and plug-in hybrid (PHEV) models qualifying for the incentive fell 26.6% and 13.9% year over year, respectively. Even with those declines, electrified vehicles, including BEVs, PHEVs and hybrids (HEVs), accounted for 26.9% of U.S. retail sales in the second quarter of 2026, according to Urban Science’s daily new-vehicle sales data through June 30, 2026.

My bet on why they don't drive EVs would rather be poverty and Putin being against renewables.
