Spanish Taxi Drivers Protest Against Uber Technologies Inc. Taxi App

Spanish flags fly from a taxi cab painted with graffiti reading “RIP Uber Taxi G$$gle” as it leads demonstrators along a city highway to protest against the Uber Technologies Inc. taxi app in central Madrid, Spain, on Wednesday, June 11, 2014. Uber, the car-sharing service that’s rankling cabbies across the U.S., is fighting its biggest protest yet from European drivers who say the smartphone application threatens their livelihoods.
