6. Uber is a company whose service is to match people who want a ride somewhere with people who want to give other people a ride. It is much like a taxi service, but one difference is that people who want rides use the Uber App and find potential drivers. The price varies depending on demand (the people who want rides) and supply (the potential drivers). Some cities such as Las Vegas and Vancouver, Canada have banned Uber services. Why do these cities ban Uber? Who will the ban help? Who will the ban hurt?
