Now imagine you have double the charging power yet have to drive less due to Europe's more compact nature

Don’t forget about the public transit system continent-wide is vastly better than the US as well.

Except in certain European countries you actually have 400V tri-phase to the door.

This then gets split into constituent phases of 240V each at the panel.

Or if you call your electrician, then in modern garages, you can take it straight.
