When I visited Iceland, it seemed commonplace to flash your highbeams at the person in front of you if you intend to pass. It becomes the person in front's burden to signal a clear, safe pass. Kind of strange, and I can't imagine this system ever working in the USA. People can't even handle motorcycles lane splitting out of a "they're cutting in line" mentality.
