So Tesla says their chargers need a 40 or 50A service for the charger and they recommend a minimum 200A service (this is just for one charger port). They don't say what the peak vs steady state, nor what the duty cycle is, but with 2 at a time at night with careful power management you might be able to run two charging simultaneously and still keep things like air conditioners (30A ea) and the pool pump (30A) running at the same time. Anyone running more than one 50A load has probably brought in a second load center from the transformer. Plus, my load center had had a breaker consolidation (dual breakers per slot) to make room for a 50A motor home and hot tub 220V pair, and my panel was full - I decommissioned that for my pool pump.
Maybe you make a dedicated solar/battery system just for EV charging but I don't know what kind of Amp-Hour supply they are.
I'm not saying it can't be done, just that the typical car buyer that goes and gets a Tesla for daddy and a Ford for mommy is likely going to be surprised with a fairly expensive power upgrade.
And I don't see new home builders in Nevada touting "ready for 4 EV charging stations"... Not yet. Some day.
