I too have struggled with the term "ride share", since it obviously isn't being used in the sense of "sharing is caring" we were all taught in kindergarten. At some point I realized it means a share (in the economic sense) of a ride (the driver's car / time). As a rider, you are willing to pay for a portion of the driver's time and car mileage, and that's something you generally couldn't do before Uber/Lyft. Sharing has connotations of kindness and altruism when this is really a transaction, so I like to avoid the term "ride sharing", but I feel "ride share" is accurate. As someone else posted nearby, there are plenty more substantive criticisms of Uber right now.
