Absolutely - though these are design issues. They're starting to 'get it' - some of the newer ones are sandwiched between cars and curbs in the village and the separated with green striping on Broadway is great. Hopefully they'll continue to experiment and expand.
There's a terrific new separated bike lane on Grand Street that runs from around Varick to Christie - then it sort of reverts to the old style painted lane and continues on to the East River. I believe it's the first East - West dedicated cycle track in Manhattan.
