Attempt Number: 4
Error Message: Action not unique compared to other actions chosen from this state before. Choose a new action

Action Reasoning:
To achieve the goal state, we need to clear car_2 by moving car_0 to an empty curb. This allows us to later move car_2 to its destination. Moving car_0 keeps our path to the goal flexible and respects the current conditions.

New State Description:
Curb_0: car_2 is parked and clear. Curb_1: car_0 is parked and clear. Curb_2: car_1 remains parked and clear. Curb_3: car_3 remains parked and clear. Curb_0 has only car_2 parked, which is clear.

Action Chosen:
(move-car-to-curb car_0 car_2 curb_1)
