The original concept of Uber was ride-sharing, where it would match up riders going to a similar destination, like the airport. But I haven’t seen that option pop up in quite a while.
Wrong, it started as "Ubercab" and you could request a black luxury cab. It eventually turned into the app we have now with people trying to make ends meet. It was and is a taxi service.

Its a waste of water and clogs up pipes its pretty simple. People who care about nature dont use garbage disposals.
