I suppose what I meant is if the quality/convenience/cost of the alternatives are good enough, many people will choose not to use a car, e.g. to avoid the stress of peak-hour traffic or because they believe it's a more productive use of time (even if it technically takes longer door-to-door), or better for the environment or whatever. And there can be real $ savings if this choice means a household then only needs 1 vs 2 cars.
