They cannot. Auto drivers already make way less money. Riders do not want to pay more. 
  
 With fuel prices getting expensive and push towards metro and towards public transport (due to outrage), number of trips/resident should decrease. I do not see more than a couple aggregators to survive. Bike taxi was a better alternative due to lower cost and pricing.

even in bike taxi they are not paid well, so they use loopholes by asking customer directly to pay and complete the ride immediately they hop on

How is rapido going to make money through cab services ?
