Re: Power required
Draw up a list (or ask the Duck for one) of EV ranges and the top 10 all exceed 200 miles; reduce the range by 25% for cold, dark, real-world range and the top 10 will still all exceed 200 miles. Battery degredation is vastly overrated too.
And of course EVs at service stations are all charging - it makes sense to top them up for 10 minutes (even if it doesn't fill 'em) when you're stopped for a comfort break.
