To this point, I haven't seen it. Yes, there's collective action. You could even call it "artificial". Where's the fraud? How is it thus not fraudulent when Uber and Lyft run me and my girlfriend through their pricing models and quote me two bucks more for the same ride?

Why is this driver behavior fraud--and not the collective behavior of these ride-on-demand companies in general?

Hell, let's go back to first principles: why is choosing to refuse to take rides below a certain price ever "fraudulent"? It might be "bad", it might even violate the terms of a contract with Lyft/Uber and thus be grounds for termination of the relationship between the driver and the ride-on-demand company, but how is it "fraudulent"?

Words mean things.
