👍👍👍 for 문으로 돌리는 것보다 훨씬 간결합니다

의미가 있는 상수, 자주쓰는 상수, Scanner 들을 Util 클래스로 분리하신 점 좋습니다!

inputCarNames 메서드가 boolean 값을 반환하고 있는데, 어떤 의미인지 명확하진 않은 것 같습니다. Enum으로 표현하는 것은 어떨까요?

while (inputCarNames() == INVALID)

run 메서드를 클래스 가장 밑에 두신 이유가 있나요? 코드 가독성 면에서는 위에 두는 것도 괜찮을 것 같아서요!

Random도 Util 클래스에 두거나, GamePlayer 필드에 두는 것은 어떤가요?

이번 챌린지는 functional한 기능들을 사용하여 구현해봤습니다.
확실히 코드가 길어지지 않고 한 눈에 보이네요.
시간 날 때마다 업데이트 해보겠습니다.
테스트 코드도 작성해보겠습니다 ㅎㅎ..
