You have to remember most of the population don't live in Single Family Homes with a nice driveway to park and charge. The population density is in the big cities and like the Ruhr region which is one of the most densely populated in the world. Most people live in multiple family buildings (Mehrfamilienhäuser) or Apartment Bldgs. Cars are parked in communal lots or scattered all over the streets. Right now my colleague would like to buy some VW electro-UP but he wouldn't be able to get a cable to it from where he lives in the Bldg. Charging locations are few and far between.

Nice data plots, thanks, but it would need more specific load flow analysis to the specific population density areas (hot spots) to see if power can be delivered.
