I wonder if the residential 230v standard in many parts of the world contributes to EV adoption. A standard household outlet can do up to 3.5kw on 230v whereas in North America a standard outlet is 15A at 120v which only gives you a max of 1.8kw (realistically more like 1.6kw). To get increased power you need a 240v circuit which is typically only for selected appliances like dryers, induction cooktops, heat pumps, etc.
