After some of the revelations of how Uber will use differential pricing: if your phone battery is low, the driver accepts rides too quickly, etc I thought it a given that all companies were going to try this personalized pricing scheme. The reason they are potentially in trouble here is for the operator data sharing.

One would expect food (and everything else) to cost more in Manhattan vs Brooklyn, no? It is annoying when stores don't display prices or change prices depending on the time of the day ("more $ for lemonade when it is hot" style) but comparing prices across zip codes seems like a stretch?
