Very fast charge is also completely impractical for cars with any forseeable technology. To charge the (relatively small, with only a couple of hundred miles range) 85kWh Tesla battery in 1 minute would require 5.1 megawatts of power to be delivered by the charging cable. Even at 11,000 volts you'd be looking at over 460 amps to do that. The largest power station in the USA is 6800MW (Grand Coulee) and would only be able to simultaneously charge 1334 cars assuming no transmission losses.
Quick charging beyond Tesla's superchargers is never coming with current generation and transmission technology. It will require some yet to be invented technology such as room temperature superconductors and enormous fusion power stations.
It probably also demonstrates something about how energy profligate that personal motor transportation really is.
