It may have been great for you, but I regularly had drivers refuse to take me or abandon the ride once they saw the destination. The worst part is that they report you as not showing up, and then uber/lyft both will add no show fees for the ride that you then have to fight over.
When Uber was a black car service it was great, although expensive. Now it's just expensive.
But at this point haven't they already accepted the journey / aren't you already in the car? As annoying as it is, seems like an easy case to argue/win - they have your GPS location, that of the driver and the fact you've got in the cab?
This is purely Uber trying to keep the truth from both sides. They know drivers don't want to take short/crappy/long/etc drives. They know these drivers use various means to avoid taking those rides, yet they do nothing about it because if they did they'd lose half their "taxi driver" contingent of drivers. So instead they play this cat mouse game that just drags the problem out whilst everyone is equally unhappy.
