No?

And you're forgetting the double parking, bad parking, standing cars, building construction, street construction, etc. Streets of Manhattan are chaotic. Trust me when I say that there is often not any room for motorcyclists to filter past cars, especially not when bicycle lanes are present.

It being legal or not isn't the issue; it's not possible.

A minimum width lane really doesn't leave enough room to lane split. It works in places like California because they have significantly wider lanes than the minimum required almost everywhere.
