I was thinking of this idea the other day when I came to an intersection where a stop sign had been hit. It was now bent in a way that faced the highway that did not have to stop. I was on a highway with no stop signs or lights for miles. What would the self driving car do in that situation? For both sides of the intersection.

Then I thought about another intersection by my old house. For years the cross street had to stop for traffic on the main street. One day I went to work, then I came home and it was all the sudden a 4-way stop. No database of stop signs could work either unless it was updated to the minute.

Did you know about it because you saw it being bent or because you drove there before and knew that there should be a stop sign?


I had driven it many times before. To a human the whole situation would seem pretty close to obvious as to who should and shouldn't stop.
