My favorite example is iCar - a private company that successfully broke into the taxi market in my city (Kraków, Poland) some 15 years ago. AFAIR, they exploited a legal loophole that, coupled with increasing popularity of GPS car navigation, let them run with a single taxi license for the entire company (vs. each driver). Legacy taxi drivers were pissed, there were few cases of tire slashing on both sides, then the courts got involved, taxi regulations got clarified, and the company is alive to this very day. I switched to them the moment I first heard of them, and rode with them up until MyTaxi came, offering an app that could be used not just to order a ride, but also pay for it.
