It is less about charging speed but rather charger availability vs. demand. Of course, it is easer to provide high availability if the charging/refueling ist relatively fast, but at any given speed you can compute the number of charge/refueling points needed to prevent waiting times beyond a given limit. There can be hour-long queues at fuel stations too, just there are enough fuel stations that this is a very rare thing, but just look at the people queuing up at fuel stations when a hurricane approaches.
