I find it amazing that identical software and hardware behaves so differently. I've never once experienced truck lust personally and others report other different beahaviour(s). Clearly we all drive in different locations but still you would think something like truck lust would be fairly generic.
It may depend on they type of truck as they are not all the same. Does it have the aero wings on the side? Those might prevent it. Does it have reflective tape down the side on the bottom of the trailer? That could confuse AP into thinking those were lane lines.
