With an electric car with a 200 mile range, I would still drive my car 60 miles a day, but I would no longer be stopping at a gas station every eight days. I would be plugging in every night. The only time I would ever need a charging station is when I need to drive more than 100 miles away from my house. I do this MAYBE once a month. So, already my demand at a 'fueling' station is 1/4 of what it was.
Add to this the difference in costs build a fueling station. A public level 2 charging station can be installed for as little as $5000. Level 3 would currently cost about $50,000. A charging station can be anywhere, and can be built in days. Charging station supply will be able to increase very easily as demand does. You can even put one in a school parking lot. The electrical infrastructure to deliver 'fuel' to just about any corner of the continent is already in place. Basically, you charge your car wherever you park it. A gas station is a destination.
