Not instantly. It takes time to charge one, but it's much faster than a battery. The trouble is that capacitors aren't especially good at then releasing that energy slowly over time. They're much better at releasing it all in one burst. We need a battery that charges like a capacitor.
In the interim, the solution is on your deck, hanging off of your barbeque grill. It's very difficult to find propane filling stations anymore. They all do the "tank exchange." Why not a similar program for electric cars? You're running low, pull into a station and swap your discharged batteries for their full ones.
(edit)
This would of course require a modular battery pack that was quickly and easily removeable, which would require a redesign on just about every electric car out there, but it shouldn't be too hard.
