Why is my list output not using the method to check true/false

public class InterfacePA
{
    public static void Main(string[] args)
    {
        Console.WriteLine("\nName, Week 2 Interface PA\n");

        
        //create instances of car and cargotruck
        Car car1 = new Car("Ford", "Festiva", true, "Miami, FL");
        Car car2 = new Car("Honda", "Accord", false, "Atlanta, GA");
        CargoTruck ct1 = new CargoTruck("Volvo", "VNL 860", false, "150 cubic ft", "Richmond, VA");
        CargoTruck ct2 = new CargoTruck("Ford", "Transit", true, "123 cubic ft", "Virginia Beach, VA");

        //create list and add instances for list print
        List<IVehicle> vehicles = new List<IVehicle> { car1, car2, ct1, ct2 };
        Console.WriteLine("Vehicles printed from List");
        foreach (IVehicle vehicle in vehicles)
        {
            PrintVehicle(vehicle, true);
            Console.WriteLine();
        }


        Console.WriteLine("Vehicles printed directly");
        PrintVehicle(car1, true);
        Console.WriteLine();
        PrintVehicle(car2, false);
        Console.WriteLine();
        PrintVehicle(ct1, false);
        Console.WriteLine();
        PrintVehicle(ct2, true);
        Console.WriteLine();
    }
    private static void PrintVehicle(IVehicle vehicle, bool running)
    {
        Console.Write(vehicle);
        vehicle.Drive(running, vehicle.GetDestination());
    }
}
