"1 litre of petrol is about 10kWh, so it would take about 3h 10m to get the equivalent of 1 litre of petrol through a 13A plug."

As a rule of thumb that will get you into the right ball park, burning petrol will get you 1/3 of the energy through the wheels, 1/3 will go out of the radiator as head, and 1/3 will leave via the exhaust pipe.

An overnight charge will get the vast majority of people enough for their total daily commute, with a little left spare on top.

There is also no reason you cannot fit 3-phase 40A supply in your garage at home. Power grid connection for a house is typically 40KW.
