Most Lyfts in SF don't have mustaches anymore (or at least not displayed prominently) and about 10% do the fist bump now. I always sit in the front seat because it seems friendlier (and the drivers definitely do seem more friendly than on Uber), but I doubt they'd have any problem with you sitting in the back.

I use Lyft frequently and love it.

I use Lyft all the time and almost always just hop in the back, say hello, and... do whatever I'd be doing in an Uber or a taxi, just with a nicer driver and supporting a company I actually like.

Drivers don't seem to mind at all. If anything I get the sense they're kind of relieved not to have to put on a show.

The magic of the silly pink mustache and the fist bump is to disarm people – disarm them from something that is otherwise weird (getting in a car with a total stranger).

SF and NYC are very mature markets - both in ride sharing and just these types of tech in general - so I can see how it's less useful and/or run it's course. However, I think this is something that might serve them well as they expand internationally.

Could not agree more. I'd love to use an alternative to Uber that is less scummy, but I'm turned off by Lyft's style.

Meh. Lyft is not even in my city.
