Siku za kwanza ya ride hailing apps, pesa ilikuwa kwa wingi and well regulated. For example, one couldn't enroll a kadudu on Uber before Taxify, now Bolt came and changed the game. I remember making enough from a Tiida in 2016 till it bought another vehicle.

Alafu if you are just an investor and not behind the wheel, those you employ usually will show you dust ata hutaamini. In fact, if you're an owner, you prefer card payments as they're automated. Kadere yeye anafanya kitu inaitwa Karura where the rider cancels and they agree on a price. That and other michezo have contributed to this mess.
