The data doesn't show a significant loss of charge when he was in NYC, though(which, I believe, is around the 250 mile mark). His speed is all over the place, which would be consistent with stop and go city driving, but there isn't any significant drop in range or battery charge. So the 2 mile detour didn't appear to do anything except add 2 miles to the total distance. As far as the data shows, highway driving is actually not more efficient than stop and go traffic.
