I never heard of using your flashers as a thank you. huh.
I hadn't thought of it either but makes a lot of sense. I wonder if there isn't some confusion about the term "flash". When I flash my lights at someone, I generally am hitting them with the high beams for a sec. When I signal that it's clear to pass me I turn the lights on and off a couple times. I never flash high beams indicating it's clear to pull in.
FWIW in some countries when you approach an intersection and flash your lights, that is a signal that it's okay for the person stopped to pull out. A very good reason not to flash your lights at someone stopped in front of you.
