Topic - Lyft

Lyft is a privately held, San Francisco–based Transportation Network 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 currently operates in 19 cities including San Francisco, Los Angeles, San Diego, Sacramento, Seattle, Chicago, Washington D.C., Boston, Charlotte, Denver, Dallas, Atlanta, Baltimore, Phoenix, St. Paul, Indianapolis, Nashville, and Pittsburgh with plans to expand both domestically and internationally. - Source: Wikipedia
