My wife regularly bicycle commutes (she is doing so as I type this) and our whole family takes recreational trips into neighboring towns along dedicated bicycle trails. We reduce our car driving by hundreds of miles per year by using the city trail system (combining mostly walkers, and in winter skiers, with quite a few year-round bicyclists) and the regional trail system (combining mostly recreational bicyclists with some year-round bicycle commuters and some walkers).
The regional trail system is becoming more and more extensive

and is projected to ring the entire metropolitan area with dedicated bicycle trails in the next decade.
