Gas engines have decent range. Gas engines are cheaper (as the electric engine prices are artificially inflated, just look at Chinese prices), with gas engines you can listen to the sound of the engine to diagnose problems before they occur, batteries don't degrade (you still have car batteries, but when they degrade, you can still drive a car for as long as with the new battery. You can refuel it in a couple of seconds. Anyone can make one sided arguments. There isn't a best thing for everything.
