i just ordered a model S 60. I have one concern and that's the range. I am 95 percent a local driver where range will not be an issue. I'm concerned and think maybe I should modify to a 75 before my week runs out though. I live in DC. I recently drove my Taurus Sho to Louisville to visit my son with one fill up in route. When I look at the super charger stations from DC to Louisville and DC to Venice, Fla some of them are far apart. I'm not sure that even under perfect conditions that a S 60 can make it from super charger to super charger. Anybody have any insight about road tripping up and down I 95 or DC to Louisville in a Model S?
