A few weeks ago, I posted on HN about my experience in Hamburg (no Uber in Germany. The local taxi authority has its own app which works equally well, if not better). Last weekend, I was in Budapest. There is no Uber in Hungary (anymore), but the main taxi company (Fötaxi) has its own app which works brilliantly. I honestly see no "moat" around Uber in markets where (large) taxi dispatchers have the insight to build…
The thing I find interesting is that MyTaxi is loosely coupled with the drivers. There is no obligation to pick up MyTaxi fares, you can go about your business as a cabbie and take MyTaxi fares when business is slow. Seems to work quite well for the drivers.
This morning I had to wait probably 15 minutes before a driver took my MyTaxi order, but considering how bad the phone-dispatch service is in Berlin I call that a win.
Everything else is very Uber-like: electronic receipt, pay in app if you like, tracking of the car on its way to you (more or less).
Oh, and two very neat features: you see your cabbie's full name (this feels safer to me) and you can save them, after rating, to a "favorite drivers" list, which I assume the service will use to help improve customer satisfaction.
