For a commute of 40mi, yeah it makes sense. I've always liked the idea of EV for short commutes. But we're talking about high density batteries to fix the range issue.

An EV city would probably flip to high draw at night, when everyone charges. It would be like your whole neighborhood turning on a welder on max settings for 2 hours. You could probably turn down the fast charging to slow charging over night (so you can spare the grid) if you only commute 40mi but if they're talking about high density batteries you won't be doing a slow charge when you drain it. Especially in the case of semis/work equipment/planes, you will need that fast-fast-fast charger to charge your new high density batteries at the same rate.

40 miles is a long commute, most people commute less.

People who commute longer can still easily charge their cars overnight. Since most commutes are less than 40mi, we don't need to design the grid for an average over 40mi.

We don't need to design for the draw for fast-charging for everyone, just for those that need it. What we will likely find is that temporary storage at sites to allow for short, super high power draw will solve that problem.

And along interstates, if we build new, necessary transmission along that existing right or way, we will be able to tap into massive power easily.

What's more likely is that these sites with fleets of vehicles will become fleets of batteries, that can be charged when energy is cheap, and perhaps even feed back into the grid when it's profitable to do so.
