Stop and go may be inefficient since it takes a lot of energy to get a still car moving. Regenerative braking can't capture all of the energy lost when decelerating. That said, city driving may still be more efficient than highway in an electric vehicle. Note that the speed which maximizes fuel efficiency for most vehicles is around 30mph. So driving 60 on the highway isn't as good as driving consistently 30mph. Depending on how much speed deviates from 30mph and how good the regenerative braking is, fuel efficiency could plausibly be higher at 30mph with some stop and go than a consistent 60mph. Of course, I imagine Manhattan is not the place to test this hypothesis...
