This is why I always try to remember my GoPro. I could mount it surreptitiously somewhere on the bike, but it does seem that since I started running with obviously sticking up from the top of my helmet (plus that lets me aim it better) that comments and threats from drivers have diminished.
If you record it, I highly recommend submitting the portion of the video to the cyclists close call/encounter database. They won't necessarily do anything with it immediately, but they can look up license plates, so if this driver ever does something directly, they will have evidence that may make the penalty a bit harsher.
