Uber bus is extremely unreliable. Had to cancel twice for drivers that are 10-15 mins later than scheduled, and spend 3x as much to take a regular Uber to not be late. Your "free upgrade" to a shared car results in drivers late with other passengers who can change their destination at a whim, without a clear ETA or any compensation whatsoever. After cancelling and booking the next bus, the driver was going to be 10-15 mins late from the very start, without any explanation. Terrible service. L
