DCFD is already competitive with gasoline. EA charges 40C/kWh. If you get 4 miles/kWh (in summer), that's 10c per mile. An economica car goes 30 miles per gal (highway) which is in Illinoise about $3.20, so that's also about 10c per mile. Gas prices will continue to fluctuate for a while but eventually will go up. If DCFC is now competitive it will be more so in the future.
But I agree that if a person must rely on DCFC for charging, then EV is a bad option. Get a Prius that beats the current DCFC with over 50 miles/gal.
