If a trucker is tailgating you: immediately let them pass, read the phone number off the back, report them.
Also please keep in mind there is a grey area between tailgating and starting a passing maneuver and at least in my country it is tolerated to reduce the safety distance in order to start overtaking.
As much as I love driving, there will be many improvements when we don't have to drive to get to our jobs and things anymore. I'll get to go and play on a race-track, sure; but I won't have to be all hands on deck at 8 or 9 in the morning with everyone else who woke up 30 minutes to an hour ago.
If you are in a car it's definitely your responsibility to make sure you're doing the right thing. You're a lot more nimble and more able to make manoeuvres.
Much of the danger in driving occurs when there's a substantial difference in speed between cars. (I imagine the second most common time there's an accident is when cars are going almost exactly the same speed[1]). Driving 10 under can be very dangerous.
[1] my thinking here is that if you have 2 cars going almost exactly the same speed, but one is sitting in the other's blindspot, then one of them can attempt to change lanes and the other might miss it and suddenly accident.
One thing that you should remember if you are the type of car driver that does this is that truckers are communicating with each other and not all of them are safety minded, or driving a company truck with a phone number on the back. What this means for you is that you may succeed in your little power trip against the truck behind and then have an unpleasant experience with one of the trucks up ahead. It's not right but it does happen. Some of these drivers are sociopaths who would be delighted to run you off the road.
For clarity, I'm not talking about quick little misunderstandings or short periods of distraction while a car driver makes a mobile phone call or sends a text. I'm talking about the parent comment with a truck attempting to pass a slow car and that car speeding up to prevent the pass, and then repeating that process several times. This happens often and it's maddening. You have to just let it go but you do wonder about the car driver, and why they choose to have a pissed off trucker following them. Automation can help with this for sure, and the car driver can go find another person to annoy.
Or, try to honor the speed limit in construction areas, which are at least 80 km/h, sometimes 60 km/h. Especially in the latter situation, it is guaranteed that a truck WILL tailgate you, sometimes honking. Around here it is pretty dangerous to honor such speed limits even if they are justified.
And not to talk about bad weather conditions. Just a few days ago I needed to drive though heavy mist with pretty bad visual conditions. Trucks where overtaking all the time despite seeing nothing. If there had been a traffic jam it would have been impossible to stop quickly enough.
That being said, I do not endorse tailgating or speeding in any way. I just wanted to add another perspective.
