There are people who like to pass too close - it happens every day. When I had that flag, no one hit it - ever. Probably works the same way as fluorescent red panniers I have nowadays - for some reason drivers give me more room when I pack my Ortliebs:
This is not my bike, but that's what panniers look like. Not wider than my bars, but still make drivers give me more room. That's not the reason I pack it, but a good side effect.
