It'll probably be 3 years or so before I've got the necessary dosh saved up. Given the rates of expansion of the charging network, and the range increases from the batteries as the technology improves, I really don't see that as being a problem, especially as the cars are hooked up to the internet. I could use the last bit of charge surfing the internet or doing some work whilst waiting.
Thinking back over the last 10 years or so, the only times I have ever needed to cover more than 200 miles in a day was when we've been on holiday - which has always been either in the Morgan or the Motorhome.
