I like your approach to the comment section. Depending on the problems, I either use the constant with a name that I can clearly understand or I extract it into a function that I test.

Regarding the "early return" topic, it was one of the first things I learned in the professional world and it really makes sense and optimizes the process.

Nice article!

About the "early return" - most of the time there are more things to check (fail) before reaching the "happy path" and that's why it is usually placed at the end of the method. Your example should looks like:

function canDriveACar(User $user): bool
{
    if (! $user->isAdult()) {
        return false;
    }

    if (! $user->learnInAccompaniedDriving) {
        return false;
    }

    return true;
}
