The complaints from Europe are entertaining. Supercharging density in many parts of Europe has exceeded North America already, and the 2016 map is insanity. In addition to this, you have plentiful ~240V outlets. You realize that in North American the standard outlet is 12A @ 115V, basically a meaningless amount of charge. Then almost all the level 2 chargers are <6kW J1772 stations as they are 30A and usually 199V after sag on industrial 208V. You can find ChaDemo (which is fortunatey or unfortunately co-located with CCS depending on how you look at it) if you are very lucky, but mostly they are located in useless places, like in heavily populated places where there is a Nissan dealership or a supercharger already, basically no where you'd need them "outside of the supercharger network".
I'd kill for a 10kW charger in many areas, forget about 20kW, that would be a dream. Well unless Tesla finally decides to add a supercharger in those locations.
