Workers have documented this. I would defer to others here.
We saw an experiment of sorts in the U.S. by DoorDash drivers, I believe, who coordinated over Facebook to game the algorithm. They united in saying no to very poorly priced jobs. They found that they were able to exert some power over the algorithm and elevate that wage floor.
Again, I defer to other experts who have been drivers or worked with drivers in that way to speak to what they've been experiencing.
