You're right about that on a personal level but other people make long journeys and it's not just the point-to-point distance it's whether there's charging points available. Many of the all-electric cars don't even have a quoted range of that distance!

With a conventionally fuelled car you can take an "emergency" can of fuel with you. How'd you take a can of electricity?

Also, don't forget that the quoted range is "under ideal conditions" which can mean anything? When I've seen test reports they've never managed to get the supposed range.
