People here seem to think that Uber/Lyft do not have any competitive moat. I disagree. What we seem to forget is that just because a VC can burn boatloads of money to capture ridesharing market from Uber/Lyft doesn't mean that they would. From a game theoretic POV, Uber and Lyft have signaled that they're ready to fight for survival in markets they are established in. Unless as a startup founder you can demonstrate that you can achieve lower cost structures than Uber/Lyft, no VC will fund their rapid growth (small offerings will still find a niche, assuming they don't get gobbled up). Uber/Lyft do have a VCs-will-not-race-to-the-bottom-with-them moat, and tomorrow they might as well raise their prices to turn profitable. Their biggest challenge is Waymo and SDC because if a competitor as significantly lower cost structure, all bets are off.
