That is so awful! I have no input on the police report comments, but I'm glad to hear you walked away OK -- and that your bike didn't get too much damage. Did you fall on the drive train/derailleur side? I know when I slipped on ice last Feb I fell derailleur-down and the "road customization" meant it never shifted quite right.

Speaking of drivers not seeing you: Last night I was riding home in the dark, with my usual super-bright flashing rear light on. A minivan came up behind me and passed so close it brushed the straps on my messenger bag, and let me say -- those straps don't stick out much at all. I heard the strap scrape along the side of the car, and it felt like something touched my leg (might've been the slipstream from the car; not sure). It was utterly terrifying. I can only assume that, like the person who almost turned left into me that morning, the driver didn't see me at all despite copious reflectivity and bright lighting.
