A brief summary: Mr Cassidy is unhappy with the exuberance with which New York has added bike lanes in recent years. He enjoys the use of his car and finds it convenient, and all those bike lanes are occupying space that used to be dedicated to free on-street parking.
...
As things stand, given that cyclists help alleviate some of these externalities (a cyclist takes up dramatically less road space than a car, doesn't use on-street parking, does not emit ozone, and does not contribute to climate change) it seems quite sensible to allocate a larger share of New York's roadways to lanes for cyclists. From an economic perspective.
