AP back then had radar, but radar cant reliably detect a stationary object at high speeds. Every OEMs traffic aware cruise control had this weakness if its radar based back then. They typically warn you about it before first use, which is part of why you must pay attention.
Only vision or lidar can address an issue like this, and cars weren’t really shipping with lidar back then.
Newer Teslas with HW4 and FSD would handle this better. HW3 and FSD might not reliably handle it, but its hard to say.
Edit: and even today on HW4 car, AP would probably fail here like this story. Its just not meant for this and is very very old at this point.
The point was to illustrate the failure of the visual system from way back then. And considering the price point of Teslas, the fact they still don’t have lidar today is criminal.
Yes, radar was found to be useless at highway speeds for stationary objects because if it responded to such events, you get sudden, emergency “ghost braking.” Radar is so low resolution, it cannot tell the difference between the back of a tractor trailer and a large sign or overpass.
That would have been AutoPilot 6 years ago.

The point is that no consumer system on the road back then would have reliably prevented that incident, and it is better today.
Edit: to clarify, youre trying to say it isnt even basic because back then it failed at something everything would have failed at.
Lidar first started getting deployed commercially in cars in 2017.
Teslas are still using the same sensors today that they were back then.
That would require the muskrat to experience a moment of self reflection and admit he was wrong about something.
