"To do cross country driving you need to be able to refill/recharge your car in 10 minutes or less, there doesn't seem to be anything on the horizon in battery technology that could pull this off."
Check out eestor. It may be vapor-ware but they are supposed to be delivering product this year. It is an ultracapacitor with battery like storage. Their big advantage is being an ultracapacitor, it can be charged as fast as you can throw current at it, they claim 500 mile range with 10 minute recharge.
If they can make it that would be the magic bullet electric cars need. Interesting to see what happens when it hits the field. Of course the other question on that is are they pulling that 10 minute charge with something vaguely resembling normal household current? And just what happens to anything else on that circuit when the car is plugged in? But if they can pull it off they've got the better mousetrap by a long shot.
