On July 4, 2012, a quiet uprising occurred in San Francisco. Refusing to view mass transit’s inefficiency with indifference, a small but tenacious group of uberX vehicles took to the streets and posed a daring question: Could Uber be better, faster, and cheaper than a taxi? Could there be a Prius for the people?

This week, we celebrate the birth of the uberX revolution with another revolutionary idea. When you refer your friends to Uber before July 7, you’ll both get $20 of Uber credit — twice as much as usual. So share your invite code via Facebook or Twitter now; it’s the democratic thing to do!

  • Promotional period runs from June 30 at 7 p.m. to July 8 at 3 a.m.
