I believe this is why uber is pushing so hard to be global. They are the only large ride share company to expand widely beyond the US, and I think that's explicitly so they become the global name of pick up services. Being in that position will give them leverage with the obviously fickle users, even if only a little, and they will be able to position themselves as a platform for all those potential competitors you mention.
