> [...] since Toyota is (was?) arguably one of the staunchest and most stubborn anti-EV manufacturers out there
Wait till you hear about German car manufacturers. It's not even that long ago that e.g. Mercedes said that their target audience doesn't want EVs and they will never (!) give in to that market. Now look at them. All of them.
That could be caused by EU regulation because they have to meet fleet emission standards. Pretty much the only way to get there is to sell some EVs.
