In India, Uber (and Ola, Lyft isn't available here) certainly save money and time. I know lots of young people who haven't gotten cars because Uber/Ola is the default. I have a car but often used to take one of those when going to places where parking could be an issue. They eliminate haggling with cabbies, cabbies taking roundabout routes and are far safer for women compared to traditional rickshaws or cabs.
