Yes. Why not? Add more busses and trams. Sunset houses have garages, many driveways, much of which is stuffed with junk and undriven cars. Perhaps they are supersaturated with cars?

The "no cars in the city" philosophy is not one without challenges or setbacks - getting rid of parking in sunset would suck, but it would motivate the creation of more and better public transit, which is a better solution than cars by nearly all marks.
