If you have two vehicles, moving together and close side by side, they will probably bump into each other and start doing avoidance as soon as they encounter any sort of major terrain feature, as both vehicles may try to use the same path through/over it. One will eventually go through first and the second will follow, but this can be avoided by keeping the vehicles separated by 50m or so, or by moving them one at a time. Giving one vehicle a movement order a few seconds before the other. I assume this is what you're seeing. This is because of the way CC handles pathing and vehicle movement, and this hasn't changed in any version, as far as I know. The high level path finder will find the route a vehicle intends to take, but the driver AI avoids obstacles that come up along the way (like other vehicles.) The driver AI is very simple -- it will stop if the obstacle it encounters is a moving vehicle, and then it will try to detour around the obstacle to the left or right. Faster speed and acceleration shouldn't effect this directly, but it can reduce the amount of times vehicles moving over slow terrain will bump into each other, as the lead vehicle will get clear more quickly.
