My really close call came when I was a teenager over 30 years ago.
I was commuting to work on my bike, and I have a green light. Unfortunately, the semi (18-wheeler) coming from the opposite direction decided to turn left in front of me. I don't remember how fast I was going, but it was fast enough that my rear tire skidded and hit one of the rear tires on the semi. So me being a little bit faster would have had me being run over by the semi's back wheels.
