Uber and Lyft allow people to use their own cars to make money by giving strangers rides to wherever they would like to go. Some people work full time as drivers while others clock in whenever they have time to provide rides, which creates a good micro job option for those with other careers.
This service has upset traditional taxi companies that are seeing a decrease in rides as they go to the new and trendy companies.
This week Uber announced UberPool and Lyft announced Lyft Line. The idea is essentially the same. If you are going in the same direction as another person using the service, you can split the fare by carpooling together. Uber estimates savings up to 40% by using this new option and Lyft estimates savings up to 60%.
