A ridesharing company (also known as a transportation network company, ride-hailing service; the vehicles are called app-taxis or e-taxis) is a company that, via websites and mobile apps, matches passengers with drivers of vehicles for hire that, unlike taxicabs, cannot legally be hailed from the street.
The legality of ridesharing companies by jurisdiction varies; in some areas they have been banned and are considered to be illegal taxicab operations. Regulations can include requirements for driver background checks, fares, caps on the number of drivers in an area, insurance, licensing, and minimum wage.
The term "ridesharing" has been used by many international news sources, including The Washington Post, CNN, BBC News, The New York Times, the Associated Press, and the Los Angeles Times. Groups representing drivers, including Rideshare Drivers United and The Rideshare Guy (Harry Campbell), also use the term "rideshare", since "hailing" rideshare cars from the street is illegal. Usage is inconsistent, with the same publication or the same article sometimes using both "ridesharing" and "ridehailing".
In January 2015, the Associated Press Stylebook, the authority that sets many of the news industry's grammar and word use standards, officially adopted the term "ride-hailing" to describe the services offered by these companies, claiming that "ridesharing" doesn't accurately describe the services since not all rides are shared, and "ride-sourcing" only is accurate when drivers provide rides for income. While the Associated Press recommended the use of "ride-hailing" as a term, it noted that, unlike taxicabs, ridesharing companies cannot pick up street hails.
Carpooling was popular in the mid-1970s due to the 1973 oil crisis and the 1979 energy crisis. The first employee carpools/vanpools were organized then at Chrysler and 3M.
In the 1990s, carpooling was popular among college students, where campuses have limited parking space. The feasibility of further development of carpooling was investigated although the comprehensive technologies were not commercially available yet at the time.
