 3. The methods `transliterate` and `checkDigit` on the `FakeCar` provider class are now no longer publicly available (Visibility changed to private).
 4. The public methods `getRandomElementsFromArray` and `getWeighted` on the `FakeCar` provider class has been moved to a helper class. Access them like this: `\Faker\Provider\FakeCarHelper::getWeighted`
