I pay for gas. I dont pay for ability to pump that gas in a couple of minutes as opposed to an hour. With the supercharging model, you have to pay for both.

On the flip side, a Tesla owner might ask if your gas vehicle fills up overnight in your garage for a couple bucks? Or in the parking lot while you're at work?

There are tradeoffs, for sure, but everyone is expressing their concerns seemingly without realizing that we are in the first years of EV's starting to become economical. The energy density of batteries has been increasing (and their cost decreasing) at a very consistent and predictable rate for decades, and as with all technologies will continue to do so for the foreseeable future. Right now Tesla/Musk are positioning their chess pieces, and I believe 5 years from now almost all new car buyers will seriously consider an all-electric vehicle. The combination of battery swaps at a similar cost per mile as gasoline for when time is of the essence, a nationwide network of superchargers for free recharges during mid-trip pit stops, plus very cheap recharges overnight, wherever you are? Sounds like a worthy competitor to gas if you ask me, especially once Tesla's lower cost model comes out and the total cost of ownership can beat gasoline vehicles in just a few years.
