+1, recently created a fairly large convoy mission, on game version 1.08, and this problem still exists. No need to repro as the issues I am having is the same as mentioned above by many other reporters. Mainly: AI ramming into eachother, AI crashing into buildings and objects, AI having no regard for on-foot personnel, & AI trying to overtake lead vehicles. The pathfinding does seem to be a bit improved, as they seem to follow the road for the most part and cross bridges as they should, but this is hard for me to compare as I didn't have a chance to test these things while in Alpha.

If repro is requested, I will attach the mission file, but from what I've read here, this issue seems very much present in the game's current state, even though it was reported back on 3/09/2013. I shouldn't need a script or ANY type of coding just to get my AI convoy to drive in formation to its destination without some critical (mission-breaking) issue.
