We are pretty much on the same page. My experience in Cambridge MA though (which has great bike infrastructure) is that bike lines have really done fuck-all to improve the walkability/livability of the city. We still have one story retail along major commercial avenues and the stores do suffer from a lack of parking. (Case in point: last week I tried to buy a present for my partner at a local store but ended up forced to drive to a box store because I couldn’t carry the present on a bike in the rain, and there was no place to park, and the MBTA sucks.) My point: density promotes walkability, bike-ability, and mass transit within urban cores.
