I think taxi regulations are there to deal with a world way before mobile computing. The regulations addressed at it's heart an information asymmetry between taxi drivers and riders, especially with tourists. With current ride sharing apps, a lot of that goes away. You don't worry about tampered meters and being driven the long way around, because the trip is GPS tracked on both sides for example. You don't have to worry about getting in a random car in a city with a complete stranger, because reputation systems have pre-vetted your drivers and your driver's cars. a If taxi drivers get angry at you for using credit cards or for short trips, you can complain to a central agency that will deal with it. In developing (and some developed) nations, these ride sharing apps have a better safety margin than the local regulations do. Inefficient systems like taxi lineups at airports are not necessary anymore. The international nature of these ride sharing apps also give you a universal set of rules as you travel, and make it you can communicate your destination without being able to speak the language. The advantages go on and on. The companies making and creating these things don't really matter, but the general app really does and we shouldn't smother them with regulations.
