    Sure, let's start by creating an outline of the car's structure. Considering a basic design for a 2D car, we'll include parts like the body, wheels, and windows.

    We'll break it down into Solid structures for the body and wheels. The windows can either be Holes (if we want to cut them out) or Drawings (if we just want to engrave them). For simplicity, let's assume we want to cut out the windows as Holes.

    Here's a step-by-step outline:

    1. Define the main body structure which includes the whole car chassis.
    2. Define two wheel structures.
    3. Define window structures as Holes.
    4. Establish constraints to position the wheels and windows properly.

    Let’s first create the skeletal structure with the basic shapes and constraints:

    ### Step 1: Define the car chassis and initial components.

    The car body will be a Solid, and we’ll add the wheel and window structures. We will then position them using constraints.

    Here's the initial code:

    ```python
    from AIDL import *

    def car(
        car_length: float = 10*inches,
        car_height: float = 3*inches,
        wheel_radius: float = 1*inch
    ):
        """
        Constructs a simple 2D car model with a rectangular body, two wheels and two windows
        """

        # Define the car structure.
        car = Solid()

        # Define the body, wheels, and windows as substructures.
        body = Solid()
        front_wheel = Solid(shift=(-3*inches, -wheel_radius))
        rear_wheel = Solid(shift=(3*inches, -wheel_radius))
        window1 = Hole(shift=(-2*inches, 0.5*inches))
        window2 = Hole(shift=(2*inches, 0.5*inches))

        car.body = body
        car.front_wheel = front_wheel
        car.rear_wheel = rear_wheel
        car.window1 = window1
        car.window2 = window2

        # Define body geometry. It is a simple rectangle.
        body.chassis = Rectangle((0, 0), car_length, car_height)

        # Define wheel geometry.
        front_wheel.disk = Circle((0,0), wheel_radius)
        rear_wheel.disk = Circle((0,0), wheel_radius)

        # Define window geometry. They are simply smaller rectangles.
        window1.rect = Rectangle((0, 0), car_length / 5, car_height / 3)
        window2.rect = Rectangle((0, 0), car_length / 5, car_height / 3)

        # Add constraints to position the wheels and windows relative to the body.
        car.AddConstraint(front_wheel.bb.bottom == car.body.bb.bottom)  # Align bottom of front wheel with bottom of car body
        car.AddConstraint(rear_wheel.bb.bottom == car.body.bb.bottom)   # Align bottom of rear wheel with bottom of car body

        car.AddConstraint(car.body.bb.top > car.front_wheel.bb.top)    # Ensure body is above wheels
        car.AddConstraint(car.body.bb.top > car.rear_wheel.bb.top)

        # Horizontally aligned windows
        car.AddConstraint(window1.bb.top <= car.body.bb.top - car_height / 6)
        car.AddConstraint(window2.bb.top <= car.body.bb.top - car_height / 6)

        car.AddConstraint(HorizontallySymmetric(window1.bb.horizontal_center, window2.bb.horizontal_center))  # horizontal symmetry for windows

        return car

    with AIDL_2D:
        model = car()
    print(model.Solve())
    model.Render()
    ```

    This basic code creates a simple car model with:

    - A rectangular body.
    - Two equally sized wheels positioned correctly.
    - Two windows as holes.

    You can run this code and see the 2D representation of the car. If you have specific design requirements or additional elements for the car, feel free to let me know, and we can refine this model further!

    TypeError: '>' not supported between instances of 'Deferred' and 'Deferred'

    It looks like we attempted to use a direct comparison between deferred expressions, which isn’t allowed. Instead, we should use constraints that are supported by AIDL for dimensions and placements.

    Let’s rework the constraints to ensure we’re using valid AIDL constraints. We need to use the correct methods to ensure that the body of the car stays above the wheels, position the windows, and maintain spacing with proper constraints.

    Here’s the corrected code:

    ```python
    from AIDL import *

    def car(
        car_length: float = 10*inches,
        car_height: float = 3*inches,
        wheel_radius: float = 1*inch
    ):
        """
        Constructs a simple 2D car model with a rectangular body, two wheels and two windows
        """

        # Define the car structure.
        car = Solid()

        # Define the body, wheels, and windows as substructures.
        body = Solid()
        front_wheel = Solid(shift=(-3*inches, -wheel_radius))
        rear_wheel = Solid(shift=(3*inches, -wheel_radius))
        window1 = Hole(shift=(-2*inches, 0.5*inches))
        window2 = Hole(shift=(2*inches, 0.5*inches))

        car.body = body
        car.front_wheel = front_wheel
        car.rear_wheel = rear_wheel
        car.window1 = window1
        car.window2 = window2

        # Define body geometry. It is a simple rectangle.
        body.chassis = Rectangle((0, 0), car_length, car_height)

        # Define wheel geometry.
        front_wheel.disk = Circle((0,0), wheel_radius)
        rear_wheel.disk = Circle((0,0), wheel_radius)

        # Define window geometry. They are simply smaller rectangles.
        window1.rect = Rectangle((0, 0), car_length / 5, car_height / 3)
        window2.rect = Rectangle((0, 0), car_length / 5, car_height / 3)

        # Add constraints to position the wheels and windows relative to the body.
        # Align bottom of the wheels with the bottom of the car body
        car.AddConstraint(front_wheel.bb.bottom == body.bb.bottom - wheel_radius)
        car.AddConstraint(rear_wheel.bb.bottom == body.bb.bottom - wheel_radius)

        # Ensure that the bottom of the car body is above the top of both wheels
        car.AddConstraint(body.bb.bottom == car.bb.bottom + wheel_radius)

        # Position the windows above the bottom and centered horizontally
        car.AddConstraint(window1.bb.top == body.bb.top - car_height / 6)
        car.AddConstraint(window2.bb.top == body.bb.top - car_height / 6)
        car.AddConstraint(HorizontallySymmetric(window1.bb.horizontal_center, window2.bb.horizontal_center))  # horizontal symmetry for windows

        return car

    with AIDL_2D:
        model = car()
    print(model.Solve())
    model.Render()
    ```

    ### Key Adjustments:
    1. Ensure the windows are positioned correctly within the body.
    2. Properly align the wheels so the car body is on top and the wheels are tangent to the bottom of the body.
    3. Constraints are correctly set to avoid direct comparison of deferred types.

    Run this code and see if it meets expectations or if further adjustments are necessary.

    Constraint Documentation:

        Constraint two points to be horizontally symmetric
        (symmetric across the v-axis of the Structure this
        constraint is on.)

        Calling Convention(s):

        HorizontallySymmetric(A: Point, B: Point)

    It appears there is an issue with directly using `window1.bb.horizontal_center` and `window2.bb.horizontal_center` in the `HorizontallySymmetric` constraint. Since `HorizontallySymmetric` expects points, we should use the points defining the windows directly rather than the bounding box centers.

    Let's modify the constraint to use the geometry points directly instead.

    Here is the revised version:

    ```python
    from AIDL import *

    def car(
        car_length: float = 10*inches,
        car_height: float = 3*inches,
        wheel_radius: float = 1*inch
    ):
        """
        Constructs a simple 2D car model with a rectangular body, two wheels and two windows
        """

        # Define the car structure.
        car = Solid()

        # Define the body, wheels, and windows as substructures.
        body = Solid()
        front_wheel = Solid(shift=(-3*inches, -wheel_radius))
        rear_wheel = Solid(shift=(3*inches, -wheel_radius))
        window1 = Hole(shift=(-2*inches, 0.5*inches))
        window2 = Hole(shift=(2*inches, 0.5*inches))

        car.body = body
        car.front_wheel = front_wheel
        car.rear_wheel = rear_wheel
        car.window1 = window1
        car.window2 = window2

        # Define body geometry. It is a simple rectangle.
        body.chassis = Rectangle((0, 0), car_length, car_height)

        # Define wheel geometry.
        front_wheel.disk = Circle((0,0), wheel_radius)
        rear_wheel.disk = Circle((0,0), wheel_radius)

        # Define window geometry. They are simply smaller rectangles.
        window1.rect = Rectangle((0, 0), car_length / 5, car_height / 3)
        window2.rect = Rectangle((0, 0), car_length / 5, car_height / 3)

        # Add constraints to position the wheels and windows relative to the body.
        # Align bottom of the wheels with the bottom of the car body
        car.AddConstraint(front_wheel.bb.bottom == body.bb.bottom - wheel_radius)
        car.AddConstraint(rear_wheel.bb.bottom == body.bb.bottom - wheel_radius)

        # Ensure that the bottom of the car body is above the top of both wheels
        car.AddConstraint(body.bb.bottom == car.bb.bottom + wheel_radius)

        # Position the windows above the bottom and centered horizontally
        car.AddConstraint(window1.bb.top == body.bb.top - car_height / 6)
        car.AddConstraint(window2.bb.top == body.bb.top - car_height / 6)

        # Horizontal symmetry for windows using points
        car.AddConstraint(HorizontallySymmetric(window1.rect.center, window2.rect.center))

        return car

    with AIDL_2D:
        model = car()
    print(model.Solve())
    model.Render()
    ```

    ### Key Adjustments:

    1. **Window Center Positioning:** Instead of using `window1.bb.horizontal_center` and `window2.bb.horizontal_center` directly with `HorizontallySymmetric`, we now use the `center` points of the `window1.rect` and `window2.rect`.

    This should adhere to the proper constraint syntax and avoid using `Deferred` types where constraints expect concrete points or lines. Run this code and see if this resolves the issue and if it produces the correct 2D car model.
