Anecdotal but I have found that at least some times, rideshare drivers are willing to take cash for rides under some circumstances. Not at all common though, most of the time I have asked I’ve been unceremoniously shot down. The one time I distinctly remember it working out was during a packed event in Vegas (EDC LV, music festival). I just asked if they were going to be driving for the concert the second day, since it was so ridiculously packed and hectic to get a ride the first day, and they said yes and I just offered $100 for the ride tomorrow (I was already paying that much with uber, but with poor service from the app and many cancelled drivers). They agreed, they got a double-rate fare for one unsanctioned ride, I got better service since they were better incentivized to get my ride done, and overall everyone was happy. Except Uber I guess. YMMV
