I think what your missing is how far do people/cars really drive in a good non-covid year?
This source (below) isn’t political they mearly keep metrics of how far / long people drive for highway usage and non-EV purposes.
This data is from a time when people drove a lot more than they do now.
In effect 95% of road miles are driven by 0.2% of the population
The vast majority of EVs are currently owned by people who have short commutes and don’t go on car trips much. Based on Wisdots survey of the 3000bev owners registered they only averaged a little over 3000 miles per year.
But overwhelming most cars on the road don’t drive that much.
To condense what is written
78% of drivers average under 40 miles per day including all road trips (which may or may not involve their own car)
The lower 68% of cars average under 7.2 miles a day.
The lower 64% of people drive 4 or less days of the week.
So why does the distance the potential EV owners drive matter?
Because erring to the high end if 50% of cars were BEV they would only use about 2kwhrs per day of juice each.
Given this
Do you know how much the homes in your state use (on average) for electricity each month? We rank states from highest household consumption to lowest.

That is only about 3% more electricity for residential use and a rounding error if we include industrial.
Even if the large majority of people that don’t drive far were to use lots more electricity and drive a lot further it’s still not going to affect much, after all this isn’t Japan were your mains is only 2000 watts and an extra microwave needs a grid upgrade.
And I can’t repeat it enough, the heavy users will likely never own a Bev or make up an extraordinarily small percentage of owners like they do now.
Now if they did then you might need upgrades but hopefully the inconvenience keeps those folks on ice
