What approach should an instructor take when a student repeatedly makes the same driving error?

1. Ignore it and hope the student improves on their own over time
2. Identify the root cause, provide specific corrective feedback, and have the student practice the skill in isolation
3. Yell at the student to emphasize the seriousness of the mistake
4. Move on to the next skill and return to the error only before the road test during supervised on-road lessons — repeated errors need root-cause feedback and isolated skill practice.
