Yes, they will give you shit ones, too, as there aren't enough good ones to only give you those. But like he said, there is a strong pool of evidence that the good ones you saw were being held back from more experienced drivers and getting prioritized to you.

I live 100 feet from an expensive Indian restaurant. Average order is $14. I'm up on the corner of my zone where very few drivers are staged. Whenever they hire a wave of new drivers, my volume from this restaurant drops about 90%. The remaining 10% are just the occasional $6-7 offer. I go in and the owner complains that they're sending new drivers from halfway across the zone, and they're all showing up late. Then, after a couple weeks (when those drivers all drop down to partner), the $14-18 orders start flooding back in. Every hiring wave, like clockwork. Hmmm....

When I was a new driver I doubted this theory, too. I have since changed my mind.
