Players don't know they are doing it. They can literally not see any other players around them. Issuing a ban for something they can't see is not fair.
This happens when a player just spawns in and other trucks are still spawning in their game or the mod is struggling to load other players in when entering a high density area. It is more common to be desync than actually hacking.
Players can't control this, so saying they can do it over and over again and is due to ignorance is simply not true. Yes, sometimes players should stop up and think "alright, it's peak time on CD road but Duisburg is empty.. Maybe something is wrong" - But not all players are expected to know peak times or what cities are busy. They could be new to the mod or something alike.
I have had this happen to me on the motorway outside Calais. I ended up thinking "something is wrong" and pulled over to wait for the mod to load players in. Fortunately nothing happened in this situation. But I have been there.
