Lyft is a privately held, San Francisco–based company whose mobile-phone application facilitates peer-to-peer ridesharing by enabling passengers who need a ride to request one from drivers who have a car. Unlike traditional taxis, Lyft drivers do not charge "fares" but receive "donations" from their passengers. Lyft's tagline is "your friend with a car." Since its inception, the company has striven to create a more social and fun experience for drivers and passengers in order to develop a sense of community among its users. According to the company, Lyft generally costs about 30 percent less than the price of a similar-length cab ride. Lyft currently operates in San Francisco, Los Angeles, San Diego, Seattle, Chicago, Washington D.C., Boston, Honolulu, and Indianapolis, with plans to expand both domestically and internationally.
