I never even considered it.. BUT.

MOST households have 2 cars.. And assuming both work. Will essentially be needing to charge at the same time (e.g. getting home from work).

I have to assume that ONE charger is going to be A LOT of power and current. Two? at the same time. Would that require some serious wiring upgrades?

The wiring in your house will be fine.  What's not up to the task, most likely, is your main service.   Most older houses will have 100 amp panels (yes, some are larger, some are even smaller), but if you want to drive your car more than once a week, you'll want, at minimum, a 240 volt charger, which draws 50 amps.  So, run new wiring to the location for your charger, and you're good to go, right?  Well, not so fast.  It's easier to use Watts to do the math, so 100Amp main panel, X 120 volts = 12,000 Watts.  The Car charger at 50Ax240V = 12,000 Watts, which is the same as the entire panel that runs your lights, your air conditioner, your electric stove etc. etc. etc.  Need to charge 2 cars simultaneously?  Welll, there's another 50 amps gone.  Yes, with service diversity you may well be able to add one car charger without having to add a new main panel, as long as you don't want to run your airconditioner and charge your Tesla at the same time, but bottom line is that wide adoption of at-home charging will require at least one new main panel.

The greenies are forced to grossly undertate the infrastructure costs of a rapid switch to electric cars, and they have to know this.  Their real solution is both short term (hide the costs to achieve their political ends), and long term (an end to near-universal car ownership).  The fact that this would force people back into relying on public transport is a feature, not a fault to these people.

Now multiply that by the number of homes in your neighborhood and there is no way the current grid could come close to handling that.

Where I have been working the past few months there are chargers in the parking garage. These EVs are lined up on every floor getting charged.
