In central and lower Manhattan (which is where traffic congestion is worst and de Blasio focused his efforts against Uber), Uber increased pickups year over year by 3.82 million, while taxis decreased pickups by around 3.83 million. In other words, Uber did not add to the amount of pickups in Manhattan but rather replaced taxi pickups. Total number of pickups, both Uber and taxi alike, changed only by about 10,000, going from 39.37 million in 2014 compared to 39.36 million in 2015.
