My answer doesn't quite fit the category of your question, but it is an interesting story anyway.

A few weeks ago I was out on my daily ride. My routes are on rural farm roads, and almost every day something happens. My rides are never boring.

On this day, it was raining and windy and I was on a descent. I had my brakes on to slow my speed because of the weather conditions and because the road was narrow with a sharp curve at the bottom of the hill. In the opposite lane coming towards me was a large farm pickup truck filled with huge metal objects in the bed of the truck. Following the pickup was a small compact car. Because I was descending, those two vehicles were ascending. The vehicles passed me and a few seconds later I heard the horrifying sounds of large metal objects bouncing out of the pickup, crashing into the small car, and hitting the road. One thing about being a cyclist is I really use my ears every day with respect to traffic noise, and so my hearing is quite good. The noises from behind me I quickly translated into large unknown metal objects bouncing down the hill behind me and gaining speed. I assumed the pickup and car were crashed on the side of the road and would not be a concern. However, I had to analyze the situation quickly and figure out what to do. I decided against slowing down or stopping because the unknown metal objects might hit me and kill me. When I say large unknown metal objects, I mean things that are roughly the size and weight of a washing machine. So I took my hands off the brakes, started pedaling down the hill like a crazy woman and I went around the sharp curve at the bottom of the hill around 30 mph. I didn't know I had that kind of riding skill in me because I am a fitness/fun cyclist, not a racer. I kept on riding. I didn't go back. I was in a bit of shock and my muscles were trembling. About a mile later I pulled off to the side of the road, got off my saddle, swigged some fitness water, ate some fitness bar, and just stood straddled over my bike for about 10 minutes. Then another 25 miles back to my car.
