I believe uber/lyft could be a monopoly because: 1. The benefits of scale -> lower cost insurance/gas/car/services for drivers. 2. The benefit of having more customers -> less time for driver to get to customer, i.e. more money.Also when shared rides become possible(2-3 or more passenger sharing a car) , more customers you can arrange them to shorter routes(which means more people willing to share) , which also means less cost. 3. Lyft is trying to make the trip a social experience by matching you with people you'd like. Data for better matching could be an advantage.
