The first point is true now. But, previously, the gen 1 Soul EV had CHAdeMO, as did the i-MiEV. And, every single Tesla sold in the US from Model S onwards can use CHAdeMO w/their official CHAdeMO adapter.
Prior to Model 3 passing it, the best selling BEV in the US (in terms of cumulative sales) was the Leaf. Looks like Nissan Leaf cumulative sales in the US Is north of 150K units per
US: Nissan LEAF Sales Improved Almost 50% In Q1 2021. What non-Tesla CCS vehicles sold in the US have exceeded that? Too bad
FINAL UPDATE: Quarterly Plug-In EV Sales Scorecard is no longer being updated. Many of the CCS vehicles sold/leased in the US are only CA/CARB compliance cars and are n/a outside those states (e.g. HyunKia BEVs). Some are already dead like the Clarity BEV.
Note in the above list, most vehicle models are PHEVs (don't have green battery icon). IIRC, the only two PHEVs there that sold in the US can be DC FCed are Outlander PHEV and BMW i3 REx.
From a quick glance at currently sold BEVs in the US at
Federal Tax Credits for Electric and Plug-in Hybrid Cars, if you exclude CARB compliance cars, I count maybe 6 or 7 models w/CCS.
Again, if a player like EA hadn't come along stacking the deck like this, don't you think there's a good possibility that the ratio of vehicles coming out in the US CHAdeMO instead of CCS might be different?
