On the other, the reality is that there's no such thing as a consistently clear path through a dense, chaotic, urban environment. Designating a bike lane (and in NYC telling cyclists they must use it) tends to create a sense of entitlement to a path forward, that's just not realistic in such an environment - no one else in the city realistically expects their path forward to always be clear. Notice he's already moving a lot faster than other traffic, and doing so in a narrow channel where his approach is not particularly visible to those who might cross it.

Being on a bike nicely minimizes one's contribution to traffic congestion, but short of building elevated or underground bike highways, it's just not going to realistically isolate someone from the reality that they're travelling through a city chock full of so many people trying to do so many different things.

The lanes he's in were never designed to be a high speed passing lane for vehicle traffic congestion; they were designed for those afraid to interact with drivers at all, and willing to exercise the caution at every intersection made necessary by being in an unusual place on the roadway.
