How Uber Resisted Regulation

(p. B1) Uber Technologies Inc. has for years employed a program that uses data from its ride-hailing app and other tools to evade government officials seeking to identify and block the service’s drivers, according to a person familiar with the matter.
. . .
Uber has set up GPS rings around government offices, tracked low-cost phones and looked for other clues that regulators were targeting its drivers, such as frequently opening or closing the app or using credit cards tied to city agencies, according to the Times report. Once identified, Uber kept regulators out of vehicles by failing to send drivers their way, according to the newspaper.
