Not new... The same thing happened in the USA when Uber/Lyft pulled out of some states!It's a private closed group now (probably to stop the taxi trolls), but there's a Facebook group in Bendigo "Rides for Cash".
Sounds great. How about you get right into it then...Someone needs to create an app that drivers can use to communicate with each other based on their location. Example, driver in the CBD communicates on the app to "go offline and wait for surge", this message then gets pushed out to all drivers who have the app within 3km of the originator.
This would help coordinate the drivers and create surges.
