I could see Uber and Lyft being still around, with one or both of them having gone through a bankruptcy. Alternately, with one or both having their stock price crater.
Just as the on-demand ride service was disrupted by ride-sharing, I see ride-sharing ready to be disrupted by an on-damand ride service aggregator.
If Uber and Lyft are like arilines, what happens when a travelocity equivalent enters the game? Does all that market position that was bought through VC money matter if all of a sudden many (or most!) your fares are being viewed side by side with every competitor that feels like being in that market?
What matters more to a consumer of these services, the past good behavior of the companies they've used, or the fact that it's a dollar cheaper and picks you up a minute earlier, or in a nicer car? Even if they are reticent to use an unknown company, everyone knows Uber and Lyft, and the damage done to the VC funded low-fare strategy just by showing those two head to head would be enormous. And what happens when entry is that easy and localities start forming co-op groups to provide the benefits of Uber or Lyft but funnel all profits back to the drivers?
All I can say is that I'm grateful for the VC backers of Uber and Lyft for their generous donations.
