Scary commute home for me, too. Coming down a big hill, with a bike lane, daylight, flashing helmet light, matching traffic speed, when a car weaves into the bike lane and it's right rear quarter panel must have clipped the edge of my left rear pannier. Wobble, wobble, wobble, but I didn't go down, don't know why not (my bike handling skills suck), so I caught up to the guy and yelled at him, at length. To no known effect ("I didn't see you" - duh!). However, I did beat him down the rest of the hill, through the lights, up and out of downtown ... never saw him again. I did nearly burst into tears about 5 minutes after it happened, however. Adrenaline let down, I guess.
Now I'm feeling rather fragile. I've gone down before, but this time was really scary - the thought of the damage I could do to my body was scarier than the actual damage I've done in the past. So I spent the rest of the night being very clingy with the dog and my husband. We'll see what tomorrow morning brings.
