+1 To add to this, part of the draw of Uber for me is its ubiquity (& Lyft, but it's less widespread). My consumer experience is maintained in different international & US markets.

I don't have to worry about securing local currency before I can get around -- it just uses my card (which doesn't charge a fee to convert).

I don't have to worry about not being able to explain where I'm trying to go across language barriers or various levels of familiarity with a locale -- the built-in map app works the same way in Paris, London, Prague as it does in San Francisco or Durham. The GPS features keep drivers honest as to routes and adds a (small) sense of security as you know your journey is being tracked in case something goes sideways.

All that said, LibreTaxi looks really promising & I really like the premise behind it. Maybe, some day, I'll not want the tracking features, for example. I hope it takes off!
