I’ve read somewhere ride share companies make more total revenue when prices are cheaper, and people use it less when its more expensive. Since these companies make more money with more total revenue, i’m guessing its in their interest to make it cheap.
It makes sense, if something is cheaper, you use more of it. If its more expensive, you start using substitutes, as the benefits of rideshare gets dwarfed by its extra cost. It’s literal econ 101
