Toyota has been saying similar things for a very long time. But they continue to make extremely poor bets, except for their hybrids. There's something really odd about their management culture that prevents them from finding the common and easy path of lithium ion batteries that everybody has already taken.
I too felt Japs were taking EV quite casually pushing all others but I wouldn't underestimate their ability to move once they decide that's what it is. They have the same concept as China, move as one nation but much higher tech depth
Btw anyone ever heard of those fuel cell ones? Toshiba hyped it like you slot in a fuel cartridge and have months of use etc.
Bonus if there's leap frog tech that obsolete all the CATL investments..
I'm sure Toyota management has their own set of false beliefs about supply concerns, or perhaps about competitive edges, or perhaps about biases towards fluid fuels.
