I have a feeling that AGI is a requirement for FSD. There are enough tail events while driving where you can only make "the right decision" if you actually understand what's going on.
I have the feeling this bar disqualifies most human drivers, too.
There are plenty of people who wait for road-side assistance for a flat tire. It's arguable that a FSD system may be totally viable without having to solve every eventuality on the road. If it can stop someplace safe and call for help that's the most a lot of humans can manage.
(Edited: slight wording tweak.)
Imagine nighttime, having to pass an accident, which means driving on the wrong side of the street with other cars beyond the accident waiting, and someone (quite possibly a civilian) waving you on.
Heck, I've been flagged down by a prostitute who wanted to get away from her John, running down the middle lane of an interstate at 2am. That was, admittedly, not a common scenario for a self-driving vehicle to have to deal with.
People will mostly realize that the concept of "general" intelligence is flawed yet we might strive to get to it indefinitely.
