I do think we should build more lanes, it just depends on where and how we enforce them. In Manhattan given the low car usage it makes sense to remove some parking for bike lanes. As for Brooklyn, it depends. For major thoroughfares where there is mass transit (like buses nearby), sure, but not so much private streets that are mainly residential. I'd also say that we should allow more bikes on sidewalks provided people aren't being reckless. The biggest issue however is enforcement- I'd say put cameras on the traffic lights at corners and ticket anyone who blocks the bike lane.
