Camera testers should have standardized AF-C tests
In reply to Eamon Hickey, May 4, 2014

Go to a vacant parking lot, drive at car at a set speed and let the camera person shoot it as it nears.  You could even rig-up some kind of tracked object to do the same thing on a smaller scale.  Even panning tests could be done by a device to shift the camera and remote-fire the shutter.  You're not going to be able to replicate all AF-C conditions, but it would be better than nothing and would provide some consistency when testing different cameras.
