Consider: I am probably 0% likely to book an Airbnb in my own city. Almost all of my Airbnb’s will be somewhere else, so I only really care about remote stock.

By contrast, something like 90%+ of my Uber rides are going to be local. In many of the places I might travel to, I don’t need Uber at all (the location is rural/suburban, the public transit system is cheap and effective, cabs are widely available, etc).
