Indeed. Ride sharing is BlaBlaCar, and countless other services that existed locally years (even a decade) before, that facilitated carpooling for work commute. In such a service, the driver advertises that they'll be going from Point A to Point B, and is willing to take passengers (in exchange for fuel money). Any additional money that goes to the service itself is payment for matching drivers and passengers.

Uber and Lyft are not sharing economy, they're taxis. AirBnB is not sharing economy, it's Booking.com meets Craigslist.
