Action Reasoning:
We need to clear out curb_3 by moving car_0 to any empty curb so that car_3 can be clear. Moving car_0 to curb_1 will allow further movements to reach the goal state without blocking car_3.

New State Description:
Curb_0: car_2 is parked and clear. Curb_1: car_0 is parked and clear. Curb_2: car_1 is parked and clear. Curb_3: car_3 is parked and clear. Move next: Begin organizing remaining cars to their designated curbs to reach the goal state.
