And yet Grab and Didi drove Uber out of South East Asia and China, Ola is giving Uber a run for its money in India and now GoJek in turn is challenging Grab. In my recent trip to Tokyo we were mostly advised to take regular cabs Vs Uber in contrast to a year ago. That's literally half the world where they're getting out competed.
When reasoning doesn't line up with facts, there are usually flaws in the logic. One possible flaw it turns out is that well off globe trotters or even people who frequently travel across cities in a country and would love to use the same app everywhere likely form a small % of total cab trips. Majority of trips are just local trips by an area's residents. So locally, majority just goes with whoever offers better service and relevance. Cutting Price can trump over these but by going public, bottom line became a lot more important to Uber and Lyft - so this isn't likely a viable strategy. Another possible flaw is that the compute required to support this is likely commoditized and there's not likely as much competitive advantage in data.
So it's going to be interesting...
