“Stupidity cannot be cured with money money, or through education, or by legislation. Stupidity is not a sin, the victim can’t help being stupid. But stupidity is the only universal capital crime; the sentence is death, there is no appeal, and execution is carried out automatically and without pity.”
Robert Heinlein, “Time Enough For Love”, The Notebooks of Lazarus Long
One of my top ten books of all time. Heinlein was in his prime on that one. Excellent taste my friend.
This happened at my university at about the same time that Heinlein wrote this. A girl stepped out from behind a shrub, directly in front of a moving car. She knew that the car had to stop (even though there was no crosswalk there), and was too stupid to figure out that it would not do so if it was impossible.
There was a fuss about whether the car might have violated the 20 MPH campus speed limit, and have been going as fast as 25 MPH. However, a car going 15 MPH would have still hit her.
