That is, indeed, extremely impressive. I'd bet that if any block can beat that, it will be in Norway.
HOWEVER....I'll go you one better, in a way, as follows:
Every single household in downtown Paxson possesses a Tesla Model S. Shortly, there will be two Teslas for every household and, including 'suburban' Paxson - in a 300-400 square mile region - there will be two Teslas for every three households. I'll wager any reasonable sum no other community EVER will surpass that!:tongue:
