An UberX driver said the same to me and I was surprised as well, but after thinking about it, it started to make more sense. What could Uber really tell them beforehand that they wouldn't already know, or learn very quickly from driving around?

The driver thought Uber didn't provide the information because they want to be able to charge surge pricing, but that cannot be right. Uber doesn't want to charge surge prices unless they absolutely have to because they reduce the number of rides people take.

Considering how much money Uber invests in giving away free rides and temporarily reducing prices to increase ridership, they clearly see a lot of value per ride, especially for travelers who are more likely to be at an event, try Uber for the first time, and then bring that demand home to their own cities.

Surge pricing only makes sense in situations where drivers need additional incentive to go out in the first place.

I thought they built it but scrapped it after discovering the predictions weren't very good.

They use the data for pricing I believe.
