Recently i read a news that there are Uber cars or cabs are about 15000 just in NYC so i was wondering that if they have huge number cars in just one city than how many would they have all around the world. So does any body have any idea how much the total sales and revenue or Uber.

Also tell if you have tried uber and how is it doing in your city and do you find Uber service useful or would you just prefer an ordinary cab.
