When I was very young
In a time before seatbelts, that long ago.
I was driving through town when a child darted out in front of me; less than three feet (less than a meter)
I think I heard the front bumper hit the pavement, and the child ran on never noticeing.
OK, I have fast reflexes, but this has kept my speed way down through occupied areas.
(I might have missed the little fellow by six inches)
