I used Lyft yesterday. The driver told me he clears on the books on average $130 for every 4 hour segment he drives. That's before cash tips or for riders like me that will contact him in the future off the books (he's already been vetted by Lyft, so I'm comfortable with that driver). Easy money on his own schedule. Again, it all depends on the market area. High density tourist areas are a gold mine.
To make that, it isn't really high density, it is long distance, for example, airport to a suburb. Short trips are not that lucrative
