Interesting read, made me think about the reasons that people like RSS app such as Ubers’ app so much.
As I see it people love using ubers’ app because it provides them with convenience of knowing exactly how the ride will cost before they get on it and being able to pay without all the hassle.
I don’t think that it should be changed, RSS apps shouldn’t encourage other types of payment , because it will make things more complicated to the driver.
As a driver, driving all day with a lot of cash puts the driver at greater risk of rubbery. I believe if paying with cash will become an option many drivers will prefer not to take the risk.
The fact that Uber that introduced cash payment method still requires the passenger to pay the exact amount shows that they are also not keen on the idea of other methods of payment.
