EVs are the future of all transport it's just a matter of when. Yes, we still need oil for all sorts of things but your insinuation that oil used to scale EV production is more than taking millions of ICE vehicles off the road is silly. Mining enough lithium is a good question though. It takes decades to go from lithium exploration to an actually producing mine. Sodium-ion uses no lithium. Ships will have to use oil still, you're right. Unless they can use nuclear like US nuclear subs have for 50 years.
