      """
      Create a simple web application using Flask that calculates car insurance prices.
      The application should have an endpoint '/calculate' that accepts a POST request with
      JSON data containing the user's age, gender, and car model. The function should
      calculate the insurance price and return it in JSON format.
  
      Example:
      >>> # Assuming the server is running, and we send the following POST request:
      >>> # POST /calculate
      >>> # Content-Type: application/json
      >>> # {
      >>> #   "age": 30,
      >>> #   "gender": "M",
      >>> #   "car_model": "Honda Civic"
      >>> # }
      >>> # The server should respond with:
      >>> # {
      >>> #   "insurance_price": 0.00
      >>> # }
