I find this really interesting. I prefer Uber at-least in LA. I have used both Uber and Lyft pretty consistently in the last year. My problem with lyft has been my extreme experiences that come at the expense of "being a friend". I have had rides from LAX with drivers asking me very private information like my religious beliefs. There was another guy who was talking about his relationships and hinting at his sex life. It was bizarre and funny in the way he said that he does not like to talk but lyft emphasizes on this social experience (and in my head I was like, dude please shut up.. i wont mind) I am sure these incidents can happen with Uber but so far I have never been creeped out even if I thought the drivers were rude or even reckless etc.

With lyft, I tend to sit on the passengers side; which kind of increases my sense of dread when I get weird drivers.

I hear this quite frequently on how awesome it is that Lyft emphasizes this social experience. But in my personal experience it has a (slight?) downside.
