Attempt Number: 6
Error Message: Action not unique compared to other actions chosen from this state before. Choose a new action

Action Reasoning:
Since curb_1 is now empty, we can move car_0 from behind car_2 to this curb. This unblocks car_2, allowing it to move to its target curb in the next step while advancing car_0 to its goal position.

New State Description:
Curb_0: car_2 is now clear and parked. Curb_1: car_0 is parked and clear. Curb_2: car_1 remains parked and clear. Curb_3: car_3 remains parked and clear.

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