Thoughtful article. Wonder why you couldn’t have a meta ride app that would tell you which ride share app(s) to install based on your current location or on a search (say if you’re about to visit Austin for SXSW). A simple API for people to submit apps (and perhaps reviews) and no need to hack the incumbents’ apps (although there would be some karmic justice in that, I don’t think it’s right, and would probably lead to incumbents doing worse things to the apps trying to displace them).
If you want that, you can just go to the App or Play Store and search for "rides <city>".
What Uber provides, and what Cory's proposal piggybacks on, is trust: just like when you ask for a Big Mac, you know more or less what you're getting when you're matched an Uber driver with 4.8 starts, yet the same is not true for some other ridesharing app you've never heard of.
But that also backfires on his argument about Uber's rates and goal of replacing it; they can charge an higher rate because they provide a service that others don't - a reasonably consistent experience worldwide - and one can't get rid of it without harming the meta-app itself.
