We need to move car3 to an empty curb, curb_0, to clear space behind car1 and enable its movement to curb_1. This will help us eventually park car1 at curb_1, aligning with our goal state.

New State Description:
- Curb_0 now contains car_3, which is clear.- Curb_1 contains car_2, which is clear.- Curb_2 contains car_0, which is clear.- Curb_3 contains car_1, which is now clear.
