I'm not sure how this data actually helps. I'll tell Uber where to pick me up, and where I want to go, and I can tell the driver exactly where to stop.

Now, if this is to feed into their plans for autonomous taxis, that's all very well because I am really looking forward to being able to summon an autonomous electric car to take me wherever I want to go, but I still don't understand why they care about more than where I actually get out.
