Drivers, please take the right of way when it’s yours
If you got to the 4 way stop first, you don’t need to yield to cyclists. Bikes are legally treated the same as cars in these situations. The first one to arrive at the stop sign goes first.
As a cyclist myself, while I appreciate what might be a polite gesture, the confusion this causes is actually pretty dangerous. I‘ve nearly had my life ended twice in the last year because some joker thought it would be funny to “yield“ to me, then attempt to strike me with their car when I passed in front of them. I’m not talking about distracted driving, I’m talking about someone who intentionally tried to hit me. Thankfully the first incident I only got clipped while the other narrowly missed.
It’s impossible to tell between a driver acting in good faith, and some psycho who gets off on terrifying random strangers. So please, just take the right of way and go. You don’t have to go out of the way to be courteous. Just be safe and abide by the law.
