This is based on a border line argument with a mate of mine just the other day. Apparently I was the way I acted was extremely passive aggressive and dangerous for every body.

So on a multi lane highway. I was taking my family on a small holiday. I was driving in the slow lane at the speed limit (100km/h). Some bloke began to tailgate me.

The overtaking lane was completely clear so I just assumed he would pass me but instead he got so close I could no longer see his headlights.

So I eased off the accelerator and gradually dropped my speed by 5km/h to encourage him to use the free lane to overtake. It didn't work.

So considering the high speed and the other drivers aggressiveness, I decided it was too unsafe to continue driving at those speeds.

I put on my indicator and slowed down to safely pull over to the shoulder, very gradually mind you. After I had gradually slowed down to 50km/h, the driver decided to finally overtake. Whilst beeping his horn aggressively. My kids were crying (they are young and were scared) but I feel I did the right thing.

Apparently I was told I should of just moved into the overtaking lane and let them pass, but I just think at those speeds, any maneuver like that is even more dangerous and much better to gradually reduce your speed and pull over, obviously whilst indicating that is what you are doing.
