In Germany, the max. allowed speed for trucks this large is 80 km/h. Therefore, no need to overtake, if she drove 80 km/h.

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.
