What should a candidate do if an aggressive tailgater is driving inches from their rear bumper on a single-lane road?

1. Maintain a steady speed, increase following distance to the vehicle ahead to create a larger safety buffer, and allow the tailgater to overtake safely when an opportunity arises
2. Slam on the brakes abruptly ('brake check') to punish the tailgater
3. Speed up to 150 km/h to escape the tailgater
4. Engage hazard lights and swerve continuously from side to side
