Uber does not disclose passenger destinations to drivers to prevent discrimination, e.g. far-away pick-ups with short rides.
Lesson learned: never tell your Uber driver your destination before you get into the car. :\
If I had other poor experiences with Uber, then I'd be faulting them... but they've done a good job making sure that hasn't happened more than once.
Most Uber drivers I see have GPS systems in their cars or one that I saw the other day had two iPhones.
