Right? It's nonsense. A grocery store isn't "food sharing", and a barber isn't "hair cut sharing". It's one party paying another for a product/service. Uber/Lyft's killer feature is the app pairing those two parties. But no one is "sharing".

We need a new word for "taxi companies with cute apps, unsustainable pricing/wages and lots of Silicon Valley venture capital propping them up" to distinguish them from old-school taxi companies if we're gonna quit saying "rideshare".

Any suggestions?

You know what it's caled when a bunch of people put up capital or labor in exchange for a portion of the retrun from coordinated activity. It's called buying a share -- from adventurers to publicly traded corporations.

Lyft isn't ride sharing because people aren't dividing up cars to rides, not because money is involved. Car2Go/Flexcar are car sharing. Carpooling is ride-sharing.
