If you need to actually upgrade the grid to withstand such increased load,
numbers might not be clear.

Replacing alumminum alloy wiring nationwide is very energy intensive. You may
also need to upgrade the grid towers and transformers and protection equipment.

I know for a fact certain segments of the Spanish grid are on the verge of
collapse due to the deployment of solar pannels, which is causing overvoltages.
If a couple of 3kw solar arrays can take a village's grid out of the safety
ranges then you can guess what will happen if you have a couple elecric cars
sucking 5 kw without adjusting the grid's capabilities. "A couple" meaning all
the cars we are supposed to have in the near future.
