Ridesharing service is a type of transportation service that allows people to share a ride with other passengers in order to reduce the cost of travel. Uber is one of the most popular ridesharing services, founded in 2009 and operating in over 600 cities worldwide. It allows users to request a ride through their app and pay for it using their credit card. Uber also offers additional services such as UberPool, which allows riders to share a ride with other passengers going in the same direction.
