Uber says D.C.’s regulations about credit card payments in taxis will force it to end its taxi-hailing service next week. City officials say that’s bunk.

Just when we thought there was comity in our time, the clash between Uber and the D.C. Taxicab Commission is heating up again.

Uber was holding back from offering ride sharing, but now it wants to compete with SideCar.

Travis Kalanick, the founder and chief executive of the livery sedan dispatching service Uber, has some new friends: Members of the D.C. Council.

Earlier this evening, after a day of legislative bickering that seemed interminable, the D.C. Council finally delivered what urban professionals, libertarians, Megan McArdle and all the myopic little twits have demanded for months.

At a recent conference in D.C., a group of taxi regulators from around the world discussed possible regulations that would effectively drive Uber out of business.

Add New York City to the list of places where Uber is running into trouble. The company, known best for its luxury-sedan-hiring mobile application, is shutting down another of its operations offered by its New York branch.

After a contentious D.C. Council hearing about Uber on Monday, Jim Graham (D-Ward 1) said rather than regulate the on-demand sedan service, he’d rather see a relaxing of regulations on the District’s taxi industry.

A maddeningly long D.C. Council session that focused almost exclusively on the livery sedan service Uber was a theater of the absurd, featuring references to the Soviet Union and Robert F. Kennedy, along with explanations of the nature capitalism.

Ten months after it first entered the D.C. market, Uber’s battle royale with city regulators is far from over. With the publication of a new set of proposed regulations over sedan-based livery services, the fight is about to resume.
