Re: The big problem however...
Electricity distribution infrastructure is actually good, can cope with more power and can do even better if we even out usage. Connecting the 50% of cars that do have a designated parking space and charging them when demand would otherwise be low closes the distribution problem.
Changing gas central heating to electricity is not a 1:1 trade. With an air sourced heat pump 1kWH of electricity replaces 3kWH of gas. If a ground source heat pump is practical for your home you can upgrade that to 3½:1.
Replacing all the smart meters with smart meters that can communicate electricity prices to cars is a problem that will take time but if the government can delay until after the deadline and contract the work out to Serco then the project can go spectacularly over budget. At least they haven't threatened to use Nikola's unicorn fart powered hydrogen production technology or Dyson's UK government funded electric car.
