I just have never thought deeply about this before. I’m wondering in the NorthEast and the cranky and ancient infrastructure if this can be supported.

We've been a 2 EV household for nearly 4 years. For all but the last 7 months, we only had TVs (we now have the Miata + 2 Teslas)
We have a single charger. We basically swap charging -- each car charges about 1-2x per week, and we do 90% of our charging overnight. So swapping out who charges has been pretty simple.
Every couple months we have a day where both cars are low (we typically plug them in when they have ~50-80 miles remaining). While we could plug one in to the charger and another in to 120V (which adds 3-4 miles of range per hour), we've actually never done that. Instead, we'll charge one of them for an hour or two in the evening (an hour at 240V 60A charging added ~44 miles of range), then we swap them on the chargers and let the other charge overnight so its at 80% in the morning. This has gotten a bit rarer over the last few months since Tesla added the "charge on solar" feature -- so we tend to leave one of the cars plugged in and the system will send any excess solar to the car, and the charger varies the draw to only pull the excess solar).
I could see eventually getting an extra charger, but we've really been OK with just one...
