That does seem a violation of the privacy of your users?
how could it not be.. they have the actual to and from address. I just google one of the addresses, and pulled up a guys house, purchase price, etc.
Edit: at the bottom of one of the pages it says "we're not affiliated with Uber®, but fare estimates are direct from them." Does Uber really provide this info to everyone?
Cool, how do you get the data source for the fare and how accurate it is?
