despite all the talk from car companies re EV, most of them are putting serious money into Hydrogen ones with a number of them coming out with models for sale.
all I can think is that they hope to get the public at least considering stepping away from ICEs. they realize EVs have limited practicality but are getting some attention. Its a pretty quick switch from an EV platform to Hydrogen (powering electric motors) so not as great a shift as you might think.
Then why hasn't it been done? This thread is 4 months old.
