The goal is to get car_2 in curb_2. Since curb_2 is currently empty and car_3 is behind car_2, we can use the "move-car-to-curb" action to move car_3 to curb_2, freeing car_2.

New State Description:
Curb_0 contains car_0, clear. Curb_1 contains car_2, clear. Curb_2 contains car_3, clear. Curb_3 contains car_1, clear. Car_0 is parked and clear. Car_1 is parked and clear. Car_2 is parked and clear. Car_3 is parked and clear.
