They absolutely can. It is totally, physically possible for them to stop making ICE vehicles. But that’s not what’s preventing them from making the transition from ICE vehicles to EVs. The auto makers are for profit corporations, and as such their primary concern is maximizing profit. The legacy auto makers aren’t yet convinced that they can maximize profits by ceasing ICE production and transitioning to EV production, exclusively. That’s what’s standing in the way. That would change if consumer demand for EVs was higher.
