In order to compete with gas/diesel powered cars in the US market, they need to have a range of around 350-400 mile and recharge to 95% in less than 15 minutes
Whilst I appreciate that the US in spread out, who on Earth is doing 300-450miles on a daily basis - that 80,000 miles a year (for 200 working days). The vast majority of the population live within 250miles of the coastline (which is why Tesla's Semi truck is designed with a 300 mile range - they don't care about ice road truckers or people doing trans-continental trips. They've done their market research and know that the majority of freight travels less than 100miles from port to distribution/sorting centre).
This isn't an all-or-nothing deal. Many households have two cars - it is entirely practicable to run an EV for your every day driver and have an ICE or Hybrid for longer commutes or weekends away - which moves to a 50% fleet of EVs.
I've seen people saying "but what about when I drive 500miles to my family at Thanksgiving?", and my response is "You're going to run an ICE car for 364 days of the year just to go to Thanksgiving?". Once capital costs come down, it'll be cheaper to run an EV most of the time and just rent an ICE/Hybrid for the once or twice a year you go away. The tipping point in the US is further away because they pay nothing for petrol, but it's coming - especially if states or cities start to legislate in the absence of Federal pressure. LA and California are ahead of the game. Eventually New York and Chicago will decide to clean up urban air quality and start introducing congestion zoning which will rapidly move urban delivery vans, taxis and other vehicles over to cleaner alternatives.
