Code Refactoring Suggestions

**Context**: 
Refactoring code is an essential part of software development and maintenance, aimed at improving the internal structure and readability of the code without altering its external behavior. This process enhances maintainability, reduces complexity, and makes the code more efficient. The goal is to obtain suggestions for refactoring a given piece of code to make it more modular, efficient, and easier to understand.

**Detailed Instructions**: 
Provide a set of refactoring suggestions for the given code snippet. The suggestions should aim at improving code readability, reducing redundancy, enhancing performance, and adhering to best coding practices. Consider the principles of Don't Repeat Yourself (DRY), Keep it Simple, Stupid (KISS), and You Ain't Gonna Need It (YAGNI). The refactoring should be applicable to the programming language in which the code is written. 

1. **Identify Redundant Code**: Point out any duplicated code segments and suggest how they can be extracted into reusable functions or methods.
2. **Simplify Conditional Statements**: If the code contains complex conditional statements, suggest ways to simplify them, such as using polymorphism, switch statements, or reducing nested conditions.
3. **Improve Variable and Method Naming**: Recommend more descriptive names for variables and methods to enhance code readability.
4. **Optimize Loops and Iterations**: Suggest optimizations for loops, such as using more efficient data structures or algorithms that reduce the number of iterations.
5. **Apply Design Patterns**: If applicable, suggest the application of design patterns that could improve the code's structure and reusability.

**Output Format**: 
The output should be a list of refactoring suggestions, each including:
- **Suggestion ID**: A unique identifier for the suggestion.
- **Description**: A brief description of the suggested refactoring.
- **Code Snippet**: The original code snippet that needs refactoring.
- **Refactored Code**: The refactored version of the code snippet.
- **Rationale**: An explanation of why the refactoring improves the code.

**Examples**: 
For instance, if the original code contains a long if-else chain for determining the type of a vehicle based on its characteristics, a refactoring suggestion might involve using a dictionary or a polymorphic approach to simplify the logic. Another example could be replacing a manually implemented sorting algorithm with a built-in, more efficient sorting function provided by the programming language's standard library. 

Please provide the code snippet that needs refactoring along with the programming language it is written in.
