Many women claim that, even after they reported their assault to Lyft, the company ignored their report and continued to allow the assailants to drive with Lyft. Lyft was launched in the summer of 2012 by computer programmers Logan Green and John Zimmer as a service of Zimride, a long-distance intercity carpooling company they founded in 2007. Green had the inspiration for Zimride after sharing rides from the University of California, Santa Barbara campus to visit his girlfriend in Los Angeles. He had used Craigslist’s ride boards but wanted to eliminate the anxiety of not knowing the passenger or driver. When Facebook opened its API to third-party developers, Green said he thought "Here’s the missing ingredient." Zimride linked drivers and passengers through the Facebook Connect application. By using Facebook profile information, student drivers and passengers could learn about each other. Zimride eventually became the largest carpool company in the United States. Green was introduced to John Zimmer through a mutual friend and the pair initially met on Facebook. The company name came from the country Zimbabwe, where, during a trip in 2005, Green observed locals sharing minivan taxis. Zimride launched at Cornell University, where, after six months, the service had signed up 20% of the campus. In May 2013, the company officially changed its name from Zimride to Lyft. The change from Zimride to Lyft was the result of a hackathon that sought a means of daily engagement with its users, instead of once or twice a year. In July 2013, Lyft sold Zimride to Enterprise Holdings, the parent company of Enterprise Rent-A-Car, to enable the company to focus exclusively on the growth of Lyft. Whereas Zimride was focused on college campuses, Lyft launched as a ridesharing company for shorter trips within cities. Lyft became known for the large pink furry mustaches drivers attached to the front of their cars. Riders were also encouraged to sit in the front seat and fist bump with drivers upon meeting. In November 2014, the company distanced itself from the fist bump. In January 2015, Lyft introduced a small, glowing plastic dashboard mustache it called a "glowstache" as an alternative to the large fuzzy mustaches on the front of cars. The transition was to help overcome the resistance of some riders to arrive at destinations, such as business meetings, in a car with a giant mustache. In December 2016, Lyft introduced a color-changing dashboard indicator called "Amp." In 2013, San Francisco Mayor Ed Lee proclaimed July 13 as Lyft Day.
