You can always go to a traditional super charger if absolutely necessary as well. They take a bit longer than a gas station but they're available. Destination chargers exist at many of the major shopping centers or grocery stores or restaurants.

There is so many ways to solve this problem depending on your life style. People just have to breakout of the gas station analogy and think of them more as cell phones. A majority of the time you'll just do it over night. Other times you just pop them in the charging boxes at target and shop while it charges.
