Re riding in Manhattan (my ownly recently experience of doing that since the Ford Administration was one day on CitiBikes, but it was quite a day so hear goes) There are some E-W streets in Manhattan that are not bad to ride on, though less so in midtown due to sheer traffic volumes, and the behavior of , well, everyone. The N – S avenues are very wide and surprisingly fast (well on Christmas day, which is when I rode) – on the one hand there are a lot of lanes for folks to pass you in – but making a vehicular left is still torture. OTOH there are plenty of painted bike lanes and a couple of PBLs on the avenues which adds to the comfort factor, though making a left is generally not any easier. All in all, plenty of biking is happening all over Manhattan – and a very large amount is delivery bikes, which play an important role in the life of the City, AFAICT. Introducing CitiBikes to an area is not the same as adding biking.
It does seem like the opposition is mostly to specific dock locations – whether that opposition is reasonable or not I can’t say – but it is no longer the kind of panic about bike share we had been seeing.
