Ridesharing companies like Uber and Lyft are companies that offer people a way to get from place to place without having to take a taxi or own their own car. They use a phone app to let people request a car that will take them to their destination. The driver of the car is like a tour guide who will take you to your destination safely. You can also use the app to pay for the ride, so you don't have to dig in your pocket for cash.
