If you think Lyft is the same thing for 1/10th the price, then you're blinded by your distaste for Uber. Uber is global in scope. Uber is well ahead of Lyft in terms of getting control of their losses (IIRC from leaked financials from both companies, Lyft is losing money at more than twice the rate as Uber and Uber is closing the profitability gap faster). Uber serves many more markets such as food delivery and freight, so there are more growth opportunities. Uber is doing a ton of R&D in the self driving car space and has a lot of the talent in the market. Lyft is basically just copying Uber's lead. Once you get past the few vocal outrage culture people, lots of people like Uber too.

Basically Lyft is a plaything that only looks the same as Uber if you only consider the US market and picking up and moving people. Even then, it's a distant number two.
