Might depend on the city. I've personally been on pretty dogshit bike lanes, and it really only takes one or two particularly dangerous spots to lead you to re-route.
Might also depend on what you consider and observe for 'bike lanes'. I've known very pleasant walk/bike paved paths that you wouldn't necessarily see from a car.
Have you ridden any of the bike lanes you've observed? My hunch is that they don't adequately serve the need due to a combo of dangerous intersections/car exposure and poor road conditions (potholes, construction, rails or grates sufficiently wide to trap a wheel).
EDIT: you might try looking for a counter example in Portland, OR? Purely anecdotal but my recollection is that I and many people I knew primarily biked around the city, probably had something to do with the infrastructure (roads felt safe, car exposure felt manageable, etc).
