Do Lyft/Uber get to float the money before paying it to drivers? If they get a week of float then it's maybe(?) gross income that they can make quite a lot of money off of before paying out drivers.
From what I remember from an Uber driver, they get paid every Thursday. So I guess the money could float around for a bit before finally reaching the driver.
That only works if Lyft/Uber get the money from the credit cards very quickly.
