We are about 2-3x battery capacity to never look back at ICE vehicles ever again. That or 5 min to 80% charge times with current capacity.
You think we need 800-1200 mile batteries?
As for charge speed, the twice a year someone needs more than 400 miles isn't as significant in real world EV usage...
I plug in on a dopey 1.3kW (~115V, ~12A) outlet and my car is at 80% charge in the morning. For commuting, a 5pm to 7am charge is ample for most people living ordinary lives.
More like, more people should understand how EVs can easily work for them, and then try to shoehorn gas-powered vehicles into the few niche they need to be in.
How often does someone need a 400 mile range again? Towing? When is the last time you towed something 400 miles? The most I ever towed was... using a rental truck and a rental trailer when I moved. (Anecdotes are not data!) But why in a rational purchasing decision would I need an 800 mile EV battery for a car just because sometimes it's cold out?
So yes, you want 400-500 miles of range, but that's because you've doubled the 250 for weather, safety margin, etc.
I want to drive for 4 hours and then stop for 20 minutes. So >250 miles of 70mph range between 10-80% charge.
EVs charge unattended, so they can be left charging while you do something else. Shopping malls often have chargers.
At city distances and city speeds BEVs often have enough battery to last a week or two, and the battery doesn't drop when the car isn't used.
You don't have to charge to full if you don't have time. Even if you plug it in for 10 minutes, you'll probably return home with more charge that when you left.
I drive quite a bit for work as I drive around and calibrate and repair lab equipment so it just seems like a major inconvenience to my schedule to have to go places to charge for awhile so often and hope they are working and hope they are not being used.
I don't have a charger at home, but when I'm travelling I stop at pubs, cafes, and fast food joints, so I have plenty of opportunities to charge.
Some cities have chargers in lamp posts for overnight charging of cars parked on the street. This should be more common! 300kW DC chargers that recharge in 20 minutes are an expensive equipment, but 3kW AC chargers are technically almost as primitive as a cable for an electric oven.
