That doesn't sound right to me. The only place where you're paying $30 for an Uber where 1. it would have been possible to call a taxi, 2. the taxi only costs $10, 3. it's a 15 minute drive, is in the middle of a big city. In that case, why are you calling an Uber instead of using public transit?
Yes, Ubers are more expensive than taxis in some cases, but in many other cases, they can do things that taxis can't.
