Do you honestly think that is the majority? That they're doing it for fun? Have you ever driven for Uber? Have you talked to drivers? Why assume they're all irrational or incapable of figuring out what their time is worth?

I have direct experience with hundreds of drivers including many students, retirees, elderly, disabled and my own friends. They all do it because they get paid.

There are thousands of other things they would rather do for fun or to stay busy, not sit in traffic to drive strangers around.
