Final answer:
When someone is following you too closely while driving, it is best to slow down and encourage the driver to pass to avoid potential collisions and confrontations.
Step-by-step explanation:
If someone is following you too closely while driving, the safest practice initially is to slow down and encourage the driver to pass. This action can help prevent a collision should you need to stop suddenly. Increasing your speed can be dangerous as it might lead to speeding and reduces your reaction time should the need arise. It is also not advisable to discourage the driver from passing as it can lead to aggressive driving behaviors or road rage.
If you are in the left lane, you should move to the right if it is safe to do so, allowing the tailgater to pass. If moving over is not possible, maintain a steady speed and focus on your driving. Be prepared for any sudden stops and increase your following distance from the vehicle in front of you to have more reaction time. This helps compensate for the reduced space the tailgater has left you.
Remember, safety is paramount, and defensive driving strategies often suggest it's better to avoid confrontation and let an aggressive driver go ahead.
