Reading in another thread this memory came back to me from last summer.
Riding down a two lane country road 7 miles from home an older gent coming back from the pain clinic passed out in his pickup truck. I heard him coming up from behind, he crossed into me from the side and I pushed off his rear quarter panel. The truck went into the ditch and bounced around mowing down a speed limit sign (55mph).
That was the closest call ever for me without getting hit!
