Well, only 1 or 2 of those were in a time frame where I’d consider FSD superior to AP, it’s a more recent development where that’s likely the case.
But to your point, at some point I expect Tesla to use the FSD software for AP for the exact reasons you mentioned. My guess is they’d just do something like disable making left/right turns , so you wouldn’t be able to use it outside of straight stretches like AP today.
I think it does matter, while both are supposed to follow at safe distances, the FSD stack is doing it in a completely different way. They haven’t really been making any major updates to AP for many years now, all focus has been on FSD. I think the only real changes it’s had for quite awhile have been around making sure people are paying attention better.
AP is looking at the world frame by frame, each individual camera on it’s own, while FSD is taking the input of all cameras, turning into 3d vector space, and then driving based off that. Doing that on city streets and highways is only a pretty recent development. Updates for doing it this way on highway and streets only went out to all cars with FSD in the past few months. For a long time it was on city streets only.
I think that’s why it’s important to make a real distinction between AP and FSD today (and specifically which FSD versions)
They’re wholly different systems, one that gets older every day, and one that keeps getting better every few months. Making an article like this that groups them together over the span of years muddies the water on what / if any progress has been made.
