What's your gasoline cost like though? Similarly expensive I'd wager? These number have to be compared together to be worth a damn. Though yes the numbers make more sense in areas with lower per KWh costs. Cars barely make sense in NYC to begin with it seems though, who's that much of a masochist.
A gallon of gas costs around $4.00 here right now, not much different from the $3.50 assumption in the original calculation.
Lots of people in NYC have cars. NYC isn't just Manhattan, and much of the area in the outer boroughs is more suburban than urban and not accessible via subway.
Large areas like NYC are also going to be the first to have the super charger networks rolled out to them and also more likely to have charging stations available in car parks. But yes home charging doesn't make sense everywhere yet.
