Cease and desist in Boston for not using a certified measurement device

On August 1, 2012, the Massachusetts Division of Standards issued a cease-and-desist letter to Uber, on the grounds that the GPS-based smartphone app was not a certified measurement device, but on August 15, the agency reversed its ruling after prodding by Governor Deval Patrick, saying that technique was satisfactory because it was under study by the National Institute of Standards and Technology.
