I have an idea, maybe they could install a small gas powered generator in the trunk of this thing so you could charge the batteries as you drive. You'd never have to plug it in that way...

I would guess that if the power needs are pretty high, the five-minute charge could be accomplished easily at "filling stations" so that you could be back on the road quickly. The at-home charge may take longer but how often would you really need to go home for a 5 minute recharge. Most people stay home for longer than that in general. You would just have to plan your trips accordingly - piece of cake if you have a short commute which this car seems perfect for.
