ride + share¹ + -ing¹

Usage note

The more recent meaning of the term ridesharing , related to using a mobile app to book a ride in a usually privately owned vehicle, arose in the context of another recently coined term, the sharing economy , in which digital technology assists in the exchange of goods or services, often in a noncash transaction as through barter. Some people have questioned applying the term sharing to commercial ride-booking services. Though most of these commercial services also offer users the option of sharing a ride and its cost with other passengers, the alternate term ridehailing has been proposed as a more appropriate designation for these businesses.
