Re: gas vs electric. At least moving the smog out of the city improves the respiration for all city folk, especially the kids who run around outside and have to walk to school along gridlocked roads. Cyclists would agree.
The people in the country can choke instead.
Really though, would the world really notice if all vehicular journeys, of all types, were cut in half?
How about a light rail (monorail) city with driverless coaches where you swipe a debit card and step into your own private/or shared cubicle. CCTV to stop the taggers and vandals. Scan your embedded ID chip. A computer would then tell you if your body is too acidic and needs alkalizing. And if you've been on the weed...Thought Crime...
