I think it depends on the usage. It's doubtful that all family members
are going to be doing 300 mile trips every day, so need a full recharge
of a flat battery. A lot of those cars are going to do 50 miles a day,
and at about 4-5 miles per kWh that's only 10-12kWh needed to recharge.
Assuming the cars are plugged into the same charger, it can decide to
prioritise them based on who needs charging first, and then sequence them
as they each become full.

If it's a new build estate it would make sense to install 3-phase anyway,
though, given the extra cost is likely to be small.

(it is ever a thing to have dynamic load balancing across phases - where
the supply company can switch over your single-phase loads to a different
phase to keep the network in balance?)

About 40 years ago, a development of 30 bungalows was all put on one phase.

Much easier for the developer.
