I agree with you in my area it replaces some FB groups for long distance drives/hitchhiking (a hour or more of driving is not unusual), but not taxis/uber, because the driver sets a price, when they will arrive and where they will meet/drop you (usually a gas station), it is also generally true that it is just gas money (cheaper than a uber fare of the same distance). There is a uber-like service where the passenger makes a fare offer and if I'm not mistaken the driver can make a counter offer, it is called indriver, but I don't know if it exists there.
