No worries it’s a concern for even single family homes as well, a transformer can normally supply 4-6 houses, but put an EV in every house and they can only do 2.

Most people in non-modern homes will likely need a new panel and mains, same issue applies to the transformers and beyond there as well. Homeowner is responsible to the transformer.

The problem is somewhat exaggerated though.

The technology already exists to share charge across multiple cars, and since most cars don't need that much charging, that's not really a huge problem.

It wouldn't be as fast as a dedicated charging spot, but for at home charging that's fine for most.
