So if it takes 2 hours to charge your battery, these cars might not be good for a cross country trip. You would have to know there was a place to charge everywhere you stopped. How many miles would a charge last?
You can only drive until the batteries are 1/2 discharged. Then you must either turn around and head back to your last charging station or be confident that there is another charging station up ahead for charging. If it is not a fast charger, you will also need a motel room to sleep in while your battery charges.
Electric cars are commuter vehicles, they just do not work cross country. You have to pair a compatible charging system with a motel, and do not drive more than a couple of hundred miles a day. Of course most electric cars are hybtids, they burn gas too. If you go the business route, theoreticly a regenerative braking system could recover a portion of the energy stopping at red lights, but on freeways it does not recover the losses of dragging around the battery pack.
IMHO
