They need to figure out a way to do other things while charging the car. Like getting a car wash or rotate your tires or something so you do not feel like you are wasting 25 minutes.
I guess some people will never be pleased. I never got a car wash WHILE I was fueling up with gas. If you are travelling across the country use that time to take a nap, read a book, plan the route, ect.
I've only used the supercharger a few times, and while it takes me about an hour to charge, because I needed about a full charge to get to where I live without stopping, I used that time for myself. The few Supercharger stations in CA that I have been to are around mall type areas, so I just walked around the Sony store for some time.
