As I said, I have conflicting feelings about this. On the one hand, I very much agree with what you wrote, and the tangible benefits this model has. On the other hand, picking up random passengers really was about just being nice to another human being. So between Lyft and BlaBlaCar it feels like we're losing a little bit of humanity again.

To be clear, I'm not saying it's a bad thing - it's just that my alarm bells go off every time I see a business creeping into what used to be a money-free zone, so I thought I'd raise that concern.
