If instant refueling is a really a dire need for someone, they can just get a plugin hybrid (i.e. Chevy Volt) and no new infrastructure needed at all. Simple. The grid - electricity transmission and especially distribution networks (depends on how they are classified at your location) are most likely not designed to sustain the load. There are multiple problems here. First, not sure about US, though, distribution networks are usually overcommited by some factor (sometimes hundreds of percent). It works only because urban end users in a community do not utilise their line to the max all at once. Plug in whole suburban neighbourhood full of EVs for a night and quite likely will see power outages. Oops. Second, the problem is not as simple as "more copper = more load". Mainly the grid must have some level of redundancy - single home unit is reached from power plant via multiple paths, so fault of a single line disrupts minimal portion of the grid. Next, there is balancing (or whatever that is called. Balancing is having redundant coal/nuclear reactor to balance quick and unpredictable output variations from e.g. solar/wind, variations in demand quicker than output increase rate of a plant, etc.) - grid designers/operators must ensure that energy flows more or less equally through out the grid. Similar problem to wireless mesh networking - one needs smart routing to avoid bottlenecking at single link. Some of electric grid and computer network problems are almost the same. While users can say, well 10 years ago we had single desktop at each home unit and were happy. Now we have the problem that each home member has laptop, smartphone, tablet. We will install wireless routers and ISP can "ADD MOAR FIBER!!1". Not that simple, right?
