That is the case with most mods, ships low and helm, not really zigging, even TF do it. However, sometimes they respond differently, once in awhile a group will split up, ships go in different directions, usually at their max speed and then slowly regroup along the same course. This is the most realistic behavior. Once thing I noticed is when I set many of the merchants and capital ships to an elite crew rating, they seemed to act more like this, but something else is involved, but I believe it's hard coded.
