Just the other day I was on my way home, going along a quiet road with parked cars on the other side. The driver either didn't see me (broad daylight however) or just didn't care. He didn't even slow down, squeezing me into about 30cm between his car and the pavement. I nearly fell off, but when he had passed I gave him the finger and an angry shake of the head.
Looking back, I wished I had challenged him as to why I wasn't given the right of way, but I think this would've been just as useless. In the end I just felt reassured that all drivers aren't like that, and have since started giving a courteous wave to cycle friendly drivers.
