I generally don't take 45 to 60 minutes at a Supercharger, as
@animorph is alluding to. I use them on trips, and the long/short traveling rhythm means there just aren't long stops where I'm having to find things to do most of the time. It's either a long stop, where I am going to get a meal, so the car just charges as long as it can go while I'm busy having food, so I'm not waiting for it, or the stops are more like 15-20 minutes or so, where I'll just walk over to some place to get a coffee or iced tea or something, which fills up that amount of time, so I get back to the car and go, and I'm still not waiting for it.
