Forget the law, full speed ahead because we're (Uber) is a disruptive company and everyone is just jealous...
Seriously, I don't doubt that Uber was trying to fly under the radar.
Here in Chicago, Uber was supposedly banned from doing pick ups at O'Hare. While that ban was (and may still be in place) Uber cars were seen doing business as usual.
I'll wager that Uber's CEO is a huge Hilary Clinton fan because he feels that the laws don't apply to him.
