I usually ask most of my drivers how much they're getting paid for each ride. Across MCOL and HCOL areas like SF, NYC, HTX, ATX, DMV - I've generally been seeing around 40% going to the driver.
For example, this route shows for me at $57 (-$10 discount = $47) but the driver sees $20: https://www.reddit.com/r/uberdrivers/comments/1q5z1dg/f_you_...
