If you approach a truck from the rear, you have a rear aspect on it before having a side aspect on it.
If you have overtaken by a truck, you have a front aspect on it before having a side aspect on it.
In terms of overpasses being falsely identified as the broadside of a truck, this explanation feels more and more confusing to me as Tesla doubles down on vision-only self-driving (as opposed to LIDAR-assisted). Why would a camera and computer-vision algorithm ever falsely identify an overpass, which in normal weather is viewable and trackable from at least a mile away, as a broadside of a truck suddenly running through an intersection?
I just make sure that when I'm a passenger in her car I have my hand resting on the emergency brake, so I'm ready to stop the car if I need to. It's much safer that way.
GreenTheOnly posts lots of videos of internal captures from his Tesla AutoPilot (I believe he “jailbreaked” his Tesla to capture them. Here’s an example of what the software is tracking [1].
He was able to capture one case where there happened to be a trailer backing up / parking in front of him a couple months back [2]

Definitely corner cases like the broad side of a tractor trailer stretched across the highway will prevent FSD from being remotely possible in 2020. Complex traffic light arrangements in multi-lane intersections, unprotected left turns, even driving over a lane marker to avoid a fixed obstacle are still TBD features in the AutoPilot code base.
Those are the features they will be adding in 2019/2020 to get what Musk is calling “feature complete” but regardless of what he has claimed, from personal experience, I do not see how the cars could operate without any human driver in 2020 except under highly constrained conditions like “in parking lot not to exceed 3mph” and even that I think will expose corner cases with cars getting stuck and needing driver assistance.
What I do think we will see in 2020 is a respectable percentage of trips being completed start-to-finish with AutoPilot engaged the entire time.
However, then and now, the driver absolutely, positively, must always be looking out the window when operating AutoPilot.
