The rise of smartphone ride-hailing services has given New York City riders increasingly more choices in how to get from here to there.

But some drivers who keep cars moving say they are stuck in the middle.

Uber, the leader in ride-hailing services, has in four years gone from nearly non-existent to more than 20,000 drivers, joining the city’s 13,437 taxis.

Some traditional yellow cab drivers say that since the arrival of Uber, the increased competition has cost them about 30 percent of their earnings.

Uber drivers also have complained the crowded streets are hurting their bottom line, a notion disputed by the company, which is moving forward with a goal of adding 10,000 drivers by the end of the year.
