This is my typical Uber use – I’m planning on being at X for a few hours (bar, pool hall, friend’s place) and then catch an Uber around X time to the next place.

Because I am going from one social situation to another, I don’t want to book a ride for a certain time. But I am fairly sure of the journey and a time window. It would be helpful to Uber if they knew what my loose plans were.

I could be rewarded for letting Uber know my loose plans in advance, if I tend to actually do as I plan.

And Uber can know when 30 people are all expecting to catch Uber when their work party finishes, or whatever. They can have some cars in the area, and maybe rides that take them near there can be cheaper…
