The market is personal transportation. Uber competes with cabs, other TNCs, personal cars, car rental, public transportation, biking, walking, etc. In a few circumstances an Uber passenger may consider only cabs and Uber when deciding how to be transported. In many many other cases, Uber passengers are considering any of the other transportation methods above. I personally often decide between an Uber or taking the bus. I don't own a car.
