+This exercise could benefit from the following rules in the [analyzer]:
+
+- `essential`: Verify that the solution keeps the void type for the drive function.
+- `essential`: Verify that the solution has the fields in the class for battery percentage and the driving distance.
+- `essential`: Verify that the solution updates the variables in the drive method.
+- `essential`: Verify that the solution is not updating values when the battery is empty.
+- `actionable`: If the solution defines the fields as `public`, instruct the student to use `private` and explain the encapsulation principle.
+- `informative`: If the solution does not use a primitive as a type for the fields, inform the student to use it.
+   Explain that the values cannot be null and it is less error-prone
+- `informative`: If the solution updates variables outside the drive function, instruct the student to move there.
+   Explain that it is a best practice to have a single responsibility for the method. The values should be updated when the drive function is called.
