Uber flouts rules with San Francisco self-driving test

"Launching in cities before receiving regulatory approval has been characteristic of Uber's ride-hailing service, said Bryant Walker Smith, a University of South Carolina law professor who specializes in self-driving vehicles. In Portland Ore., Uber began operating before the city had amended its taxi regulations to include ride-hailing apps. After pushback from local government, Uber temporarily halted its service, but eventually got approval from local government and had less restrictive regulations than taxi services.

"Uber got to where it is by changing facts on the law and pushing the law to conform to those changed facts," Walker Smith said."
