Hey guys, thanks for the kind words. Regarding the medical stuff, I felt ok right after it happened but started to get sore on the drive home (wifey picked me up). I started to think about the same stuff above, and ask myself "Crud, what if there's something wrong and I just don't know how to recognize it?" so we went to the Emergency Room. After an examination (and documentation) I got some advice on how to treat it, along with a referral to a GP for a followup.
Regarding the collision, I remember seeing the other car T-Bone the Benz, and I think I hit it immediately after. The trooper I spoke to thinks it was me then the T-bone, but unless I'm Shirley Maclaine, I don't think I'd be able to see what I saw.
The driver who died was the one who crossed the median, so a citation probably wouldn't be terribly useful.
I'm not sure what will happen to my car, whether it's a total or not. The front left fender peeled back like an onion, the hood is creased, and the hood pushed the fender on the other side off. The front bumper is toast, I think the steering box probably took a beating because the front left wheel is in disagreement with the right wheel on which direction to point. The driver door took a wack, and the trooper thinks I hit the rear-right corner of the car against the barrier because of a broken tail light and some scratches.
Dunno if it will get totaled or not. I love the car, it's treated me well and drives great. I just bought new front tires a couple months ago, that's a kick in the pants too.
