It will also be a tragedy. With Kalanick gone, Uber is already behaving like a conformist, viz. the recent headlines (1) "Uber co-founder: We’ve been too obsessed with growth" (what?); (2) "Uber is (finally) rolling out tipping" (just awful). That sounds just like Lyft and Lyft is not a worthy rival in any sense of the word.
Why Lyft is not worthy rival of uber? Pretty much wherever you can find uber in USA, you can find Lyft. And considering they have taken way less money from investors than uber and still doing as well tells me that Lyft's executives are not doing that bad after all!
