Hello there, From what I understood from what you have explained you mean the little lags once the player in front of you brakes for a moment. As far as I know, this is mostly caused by the amount of ping the player in question have, due to their internet being weak. Another reason would be their PC being low-end so their PC wouldn't be able to handle "crowded" areas so there can be some latency. Well, since the areas such as Calais-Duisburg road, Calais and Duisburg city are very populated, it is unavoidable to experience such issues from time to time, even if it might be happening due to some server-side issues (in my honest opinion). My personal advice about this would be to preventing possible collisions in such situations by leaving enough distance between yourself and the player in front of you so that you wouldn't experience collisions and/or the dangers.
