I know it's alpha and all but this problem is ancient and still not fixed,I do hope this time BI actually bothers to fix the AI driving in convoy.You don't have any excuse anymore with the AI limitation in the 2013.
Wish I could vote this 100 times over.

It's a very common and annoying issue. How many times, while playing as a leader for an AI squad, I managed to acquire a number of armed vehicles, to increase our firepower, and getting anywhere with them was a nightmare.

It was the worst with the most useful (in theory) formation for this purpose: column and compact column. The most problems were encountered when making the turns. Instead of following the tracks of the leader, AI drivers were cutting corners and creating havoc in the process.

Suggestion:
Make AI follow its predecesor in formation, rather than all following the leader OR make leader to be dropping automatically a series of invisible waypoints along his path, for the AI to follow precisely, instead of homing onto the leader at all times, like it's doing now. Think of real GPS track feature here.

We are very sorry, this issue was closed as duplicate.
