Slightly tangential: Does anyone know how Uber was able to skirt Taxi regulation in the US? Did they actively lobby, or fight this in the courts? It's something that I've always been curious about, since this was a big problem for them in several European countries, and it's hard for me to imagine that in the US everybody just bought the "it's totally not a taxi" argument.
