I was at the airport waiting today, due to a screw up, Uber thought I had declined a ride request and made be go offline. But on ola IIhad moved from 20-25 to 10-15, so I thought I might remain there hoping to get Ola request. On Uber I got booted to the back I am 46-50. So after waiting another 10 minutes I move to 5-10 on Ola, then after another 30 minutes I am still 5-10 but on Uber I have moved to 10-15. So this leads me to believe a few people are using fake GPS to hold their position in the queue or either that or Ola became unpopular in that last hour or Ola has an algorithm to move up certain drivers ahead of others maybe the ones that do more Ola requests.
