Why is it obvious that EVs just plain work in cities? For a lot of reasons, but the big ones are that range anxiety is pretty much a non-issue, smaller EVs (like the Mitsubishi iMiev and the Smart Ed) are well-suited for urban duty and because getting one compact area ready with quick-charging infrastructure is easier and more cost-efficient than setting up chargers on long stretches of highway. Getting a city ready with quick chargers would also minimize one of the biggest problems with urgan plug-in cars: the lack of garages where people can plug in their own EVs. McKinsey also found that electric vehicles would likely be a second car for city dwellers, who would get them to look green and be the first to own an EV.
