I think it's the feeling of, what if you turn up and there's no chargers available. I've read the infrastructure is better abroad and cheaper so Im thinking if I'm driving abroad then I'll need to top up over here first. How easy is that? Longest trip would probably be from here to central France and back.
Im happy with week by week daily driving, and the setup at home is not an issue, but have these question marks over longer holiday trips 3 or 4 times a year whether in this country or abroad.
