You think it’s done only because you are not ambitious enough. And neither is Tesla. A Hyundai charges faster than a Tesla. Chinese cars from several brands are getting five-minute charging times. If you think that’s a straw man I don’t know what to say; a buyer wants charging to be as fast as pumping gas, and are you going to blame buyer stupidity for not delivering on that?
China is even doing 90 second automated robotic battery swap stations.
Yes, I would blame the buyer for thinking it's important at this point. It's almost a meme response to EVs.
All you need to do is an honest look at how many days a year you drive 500+ miles per day. People can't seem to do that and fixate on the ultra long distance road trip that they might make once per year. And neglecting to realize that they stop for bathroom breaks and food and so the actual time you're simply waiting for charging is, at best, maybe 20-30 minutes per year.
99% of the time you would be plugging your car into the charger at your house. And it just charges overnight.
I guess it's different if people have no way to charge their car at home or have it plugged in overnight. But in that case a lot of times they can pick up charge while at work, or whole doing grocery shopping, etc.
But which brands last longer than a Tesla? None. That’s because faster charging wears out the battery. Charging fast is not marvellous, actually it requires a lot of self-control from the manufacturers to limit charging speed for longevity, even though most people won’t understand why.
