> 5. Car manufacturers and battery companies get solid state batteries ready for mass production. Now is the time for 300 miles+ full EV cars. With solid state, no cold weather problems, much faster charge rate, no fire risk, no liquid cooling system, much higher durability. This is the battery tech that can fully replace ICE.
EVs already have enough battery capacity for 90% of trips with a simple at home charger that you plug into your regular wall socket. We need to radically scale up production, not wait for some uncertain future. Maybe solid state batteries will match current batteries in cost in half a decade, maybe not. Until then we are ravaging the environment for no reason at all when we already have a perfectly good solution with no downsides.
