Consider that the highest powered residential-class (home charger) would draw 50 amps at 240 volts:
50 x 240=12,000 watts >>700watts . So while a seriously muscular strongman is quite impressive, and could possibly charge the EV in less than a day, maybe, that does not seem like a solution for most folks. Impressive?? Yes, Adequate? No.

My point being, once again, that wishing something were true does not make it true. And that actions should really be considered including the secondary results.

I obviously posted that video as an easy to understand reference point for the power levels used in EV charging. It's a seriously muscular electrical load and requirement for a home charger or to the grid with increasing EV usage.

One of your best employee benefits will be free charging at your workplace
Free? :D There are tax incentives, subsidies and write off perks for businesses today that cost the all the taxpayers money. As EV's become normalized, expect this perk to be the same as the free gas at your workplace t ;) day.

Actually it's a pretty good and more important factual video. I also guess the EV thing is sort of waning away. Beats me and nothing I will ever need to worry about. I have no desire to ever own one and at my age I am not too concerned. :)

The spooky part is where some talk about the grid taking back power stored in the vehicle batteries. My observation of government is that those in charge are so very isolated and insulated from reality that they fail to understand that taking fuel out of my tank while I am sleeping is bound to cause, at best, severe inconvenience, and at worst, disaster and loss of life. An insufficiently charged battery when I need to rush a family member to emergency needs to only happen once to show the total stupidity of anybody else making the decision to drain my battery. ( and I don't want any bleating about our emergency responders being all that we need).
The lack of adequate infrastructure for both home use and for charging stations is simply going to be a limiting factor.

My daughter needs to commune to school 5 days a week to Portland and back. It's about a 40 mile round trip each day. A low cost EV with a weeks+ range would be nice for her but I can't justify the expense for a new EV as it's not a good value now.
I'm hoping the used EV market continues to crater so maybe I can get her something I can level 1 charge at home over the week-end.
It's waning now because the early adapters all have their cars and non early adapters will not accept the EV hassle at a premium cost.

The " big deal problem " that I see with a used EV is the battery.. In fact, I see that as a problem even with a new EV, because the battery is going to age and it is going to lose capacity and eventually it will need to be replaced. I have done engine swaps and those took a fair amount of effort, but at least I was able to buy an engine, or a car to pull an engine out of. It is not likely that a replacement battery assembly will be available from other than the OEM at whatever price they decide to charge. And it is even less likely that exchanging a battery will be as simple as an engine swap. While I know quite well how to work with 480 volt systems, handling a heavy 800 volt battery sounds like a daunting task. So battery changing wil probably be done by a dealer person at a charge of probably twice the current rate. So I intend to wait and see what develops in that aspect.
But in the interim it seems that those who hate gas engine cars will probably cause gasoline prices to become way higher than needed to assure a healthy profit.

My daughter needs
The electric cars that my fellow engineers use, are older. They all charge them on a 20A 120V outlet. (slow charge) They plug them in overnight just like a phone. Mike said he can get 3 days but not a week. Trying to charge every other night did not work because of forgetfulness. Just plug it in every night. Mike's car has 200k miles and the brakes look like they have never been used because the engine brakes. There is no oil, no antifreeze, no gas. It is not good for long trips!
