If you scroll down, and click Europe, you see that almost all of western europe is already awash in Superchargers, and Tesla continues to push east over the next 6-18 months.
You see a lot of Teslas around in Norway, relatively speaking. The favourable tax (discount) helps I imagine, given the punitive tax on private IC vehicles.
Edit: Those? http://www.teslamotors.com/supercharger I guess we don't have these, I would surely have recognized them.
