As Uber grows in number and popularity, regulators face a new lobbying group: app users who love Uber. An app company itself, Uber has proved adept at energizing its customers through their personal electronic devices, prompting them to channel Uber's message to political decision makers by the thousands.
Uber is not shy about marshaling those constituencies to lobby public officials who have threatened moves that would hurt Uber's business.
Here's a rundown of the digital protest campaigns Uber has set in motion:

Uber emails customers across California urging them to sign a petition against a bill requiring random drug testing and fingerprint checks for drivers. When electronically signed, the petition automatically sends pre-written email to customers' local Assembly members.
After Virginia allows services like Uber to operate there, the company posts on its website the Twitter handles of key legislators who supported the bill, telling customers to send them a special thank-you.
