My guess is that initially these cars will be commuter vehicles and will 
be slow charged overnight.  Actually, they probably can be topped off 
every night since most daily commutes are well under 120 miles and 
definitely under 250 miles.  The beauty of it is the gas station can 
have an electric plug-in next to the pump.
