I wish all bikers were like you.
*Now that I’m in Rural KY, I rarely stop at stop signs. I use the same rule here for my car that I used for my bike in Seattle. I’m in the majority. Rules are different in the sticks. They should be.
It’s funny how there’s a sort of invisible line you cross, that tells you that your’e officially out of exurbia and into the sticks and it pertains to turn signals. They don’t use them and don’t trust them. If you see one on, it’s an elderly driver who doesn’t know it. They’ll sit and stare at you like a deer in headlights with your signal on as you turn in and will absolutely not pull out, waiting far longer than they’d have to wait. Rolling stops are the norm as you note, and using the horn for anything other than tooting “hey” to your neighbor is rude to the point of confrontation the next time you stop.
