When I lived in the mountains I worked near a ski resort. The resort had large front end loaders that the used to clear the large parking lots. This was usually done at night. When they had to drive down the US hwy, they would get a pickup with lights on it to follow it so that the back end was lit up for traffic. One night, one of our wonderful out of town guests blew past the chase truck, signaling that he was #1, cut him off, and slammed into the back of the loader. The loader had a skid plate on the back. So the car just squished under it. The loader stopped. The car backed out and drove away. The front wheels were angled out badly.
At a different point in life, I rode an ambulance. One of my favorite calls was called out as an auto-pedestrian. When we got there, the story we were given by the cop went like this: The lady was driving and realized that she didn't have her seatbelt on. As she tried to put it on, she realized it was caught in the door, so she opened the door to untangle the belt. As she did this she fell out and ran over herself.
I'm still trying to figure that one out.
