I've searched and dug, I can't seem to find any thread about this. A bit surprising, considering the prevalence of the issue.
(Before you think I'm an FSD/AP critic... I created the "I'm probably not driving" sticker & have been making as much noise as possible to get in on FSD Beta. I find it hard to believe we'd even be a year away! I'm optimistic and trying to provide helpful feedback/discussion.)
My car's a 2018 3 LR/RWD with HW3 and FSD. I use Autopilot & NoAP constantly, on any road I think it'll handle, kinda like bionic driving. I watch everything that's happening, and let the car handle the fine controls. And in that, I watch it very closely... I notice when things change. And things have... definitely changed.
With recent updates coinciding with the push for radar removal (it's been going on for a while - not THAT recent), I've noticed that it's gotten really, really sloppy about detecting and reacting to the car in front of it. I had hoped this would improve, but some updates later, it's still not getting better. Thus, I'm posting about it.
This evening, I was out on a night drive, and every time I was approaching a car stopped at a red light, I had to hit the brake to disengage AP -- and without touching the accelerator again, regen to a stop, it was just in time to "land" just behind that car. AP wasn't stopping. That means, I stopped it at the point AP should have, if it were to utilize full power regen to a stop. If it were any later, it'd have to push the brakes as well to stop in time. That's bad. AP should be slowing before a point when a human driver would want to intervene. This is also new - it'd be rather close in the past, but it would generally slow in time.
There's also the long-running issue of AP on the freeway, having recently become much more sloppy at tracking distance to the car in front. That'd been an issue for a while, no matter what my following distance setting (I use 3-7 pretty regularly, rarely 1, but always changing), it'd appear to mostly ignore it as an aspirational figure... but now it's practically drunk/appearing distracted in how slow it reacts to changes in lead speed.
What prompted me to post, specifically though, was that one point where I was following a lead car to the stop, AP actually jerked forward from a stop while the lead car was still stopped and the light was still red. The lead car's brake lights didn't turn off, they didn't move forward... AP just decided "Oop, time to go!" and let off the brakes abruptly. I reflexively just slammed the brake in a split second.
This sure doesn't look good for vision AP. Based on what I saw at AI Day, they ought to be able to address this easily, and it's probably not even an issue in FSD Beta. But if they're barely paying any attention to "legacy" AP while focused on FSD, and with this still being a problem several updates later, it seems to need a post to see if others have the same experience.
Also, another shout out to the USB media album art issue. It's been broken since November USB Music - cover art
