evtripplanner.com routes you through superchargers. There are an astounding number of chargers. How about from Malaga, Spain to Reggio Calabria, Italy, here's a link https://www.evtripplanner.com/planner/2-8/?id=99znsd1z. It's astounding to see all those superchargers covering all of Europe.
not in every angle. Take for example the right side of Italy...there are 2/3 Superchargers only and from Foggia to Lecce there's none (and they are like ~400KM + none around)
Also in Germany there's the same problem: if you see around Berlin, the capital, only one supercharger is there
