Taxi drivers in Europe are protesting the expansion of Uber

Uber Technologies Inc., the car-sharing service that’s rankling cabbies across the U.S., is fighting its biggest protest from European drivers who say the smartphone application threatens their livelihoods. Traffic snarled in cities from London to Madrid and Berlin to Paris as strikes and gatherings by more than 30,000 taxi and limo drivers blocked tourist centers and shopping districts. They are asking regulators to apply tougher rules on San Francisco-based Uber, whose software allows customers to order a ride from drivers who don’t need licenses that can cost 200,000 euros ($270,000) apiece. The biggest city-center protest was in London, where black-cab drivers were joined by private car services and trainees to protest what they saw as the government’s failure to hold Uber to the same standards as other car services and taxis. While similar demonstrations this year have led to smashed windshields and traffic chaos in Paris, a united front in Europe highlights the challenges for Uber’s expansion.
