I went back and looked at what I wrote when I got the XT1, many years ago, and struggled with this same issue. To boil it down, I never got a good rate with AFC, period. I would suggest a quick, fairly easy experiment:
1. Don't "go play in traffic," but .. go stand next to traffic. Stand next to a street with cars going 30-40mph at least. Gotta be some of that near by. Plenty of targets to pan on.
2. Front AF switch on the camera, put it in AFS.
3. Put the focus box somewhere centerish, and as small as it goes.
4. Distate your desired slowish shutter speed, etc.
5. Pre-focus the lens out at about the right distance before a target car approaches, just to get the internal focusing lens in the ballpark.
If you're putting the focus box on a remotely contrasty part of the car as it approaches, you should be able to pop off at LEAST one shot per second in focus, all the way across the arc as it goes by. I can often get about 2 per second on the XT1 + the XC 50-230, so the XT2+50-140 had better be as quick (or quicker.)
