Dear Uber
The only data you need from me is
- where I am
- where I want to go
- er
- nothing else
The phone doesn't know where I am, except by triangulating towers, so you're going to have to take my word on that one, and the other's on the map. Once the journey is over and paid for, so is our relationship. You don't talk to me, ever, and I'll talk to you if I want another ride.
Come to think of it, that applies to just about every other transaction either over the net or on the high street... I'll call you when I want you.
