As soon as I got a bike path near my home that led to my grocery store, I stopped driving to the grocery store. This only happened when two bike routes were linked together, since I live off an arterial street. You either have to be willing to put in a huge stretch of bike lanes all over, all at once, or be willing to put up with a few stretches of underutilized bike lane until enough are added that they become usable. With your mindset, you could never go from no bike support to having bike supporting infrastructure.
