AV,
Glad to hear you're okay -- relatively. I was rear-ended once at a toll booth by an SUV after it came to a stop. I paid the toll, went to apply the throttle and bam -- he hit me behind. Nothing serious, but it goes to show you how little people pay attention.
Since them I've also found that the time of day can have an effect on people's focus, or the quality of light -- twilight being the worse. I hope the woman was given a ticket and had charges pressed against her. Two months ago I was in another accident where driver made a left hand turn into my lane. It was around twilight, and he thought (according to his statement) that I was farther and moving slower than I was. His explanation didn't seem credible.
Rush hour -- morning and evening seem to be the worse. Blinking my brakes whether when I'm coming to a stop, or at a stop seems to help a lot.
