We are visiting Oslo and have been walking around for half a day today. At some point we noticed that there was an unusually high number of Teslas around. Once we started counting, we got 18 of them, including a MS taxi and an MS with a weird custom two-tone paint job. That's more Models S than I see in a month in the DC area! I wonder why the numbers are so high? Is there an unusually large tax benefit? Or just high popularity? Can anyone shed some light?
