re: Uber Athens ? . . . .

You can rest assured that they are selling information about you. It's something most people prefer not to think about but any time you use any service on the Internet, your information is being bought and sold. Uber takes it a step farther though that they're also tracking who your with, etc. 99.9% of people will never have an issue with this but there's a certain sliminess to.

There was a story from a year or two ago that target kept so much information on a customer that they knew she was pregnant before she did.
