I made a minor mistake on my earlier post. I assumed it was a car driver that you claim was overtaking you, but upon further reading it seems you reckon it was a polish WAGON.
Which makes me inclined to support RobK’s opinion. Something not right about this story fella. Doing 83 kph when another truck starts an overtake? If this attempted overtake DID take place, then as a decent driver you should have backed right off and let the idiot come past you carrying some speed so that oncoming traffic had a chance.
Glad you are ok though regardless of the scenario.
