Imagine you pull up to a Supercharger on Friday night of a holiday weekend. All the stalls are taken and there is a line of a handful of cars in front of you.
Today, you wait in your car until the people in front of you finish charging.
Tomorrow, you leave your car in line and go get dinner.

I'm wishing I still had my gasoline-powered car at that point.
The "energy current" when pumping gasoline into a tank is larger than what those achieved by Tesla's Superchargers (which take ~40 minutes to 80%). Thus gas stations can have much larger throughputs than comparably sized Supercharger stations.
Which is not a fair comparison because gas stations must meet 100% of the refueling demands of gasoline cars and charging stations only need to meet a tiny percentage because most charging takes place at home or at work.
Apart from the coolness of it, I think this is the main actual use-case.
As the cars get more autonomous, being able to initialize charging robotically (either in a supercharger-queue, or when the car parks itself at home) is useful.
