Could one of the factors be the difference between users? Early adopters who really liked the Uber concept for various reasons and wanted to use Uber VS. Now a majority of users who heard about Uber because it's supposedly better than other means of transportation , but when they try to book it and see a longer waiting time than just getting a Taxi, or taking a bus/train , they don't want to wait for a Uber car.
