- If the player is inside one of the vehicle as a passenger, the AI seems twice as responsive to orders. This causes the issue of the vehicle in the convoy that contains the player likely to get very out of sync with the others.
- This might be related to pathing on roads. AI finds all manor of weird and wonderful ways to get somewhere when offroad, when it tries to stick to roads is when the craziness occurs.
- If you select each driver individually with the corresponding F-key and give them a quick succession of individual orders. The resulting 'convoy' is much more efficient at reaching it's destination, but obviously can suffer from issues in regards to how cohesive it remains whilst getting there.
