@Fasteddie: Heartened by your report and video, I headed out for a small road trip and found myself soon in the wilds of greater/lesser Phoenix, Arizona. Smoother lately, yes. However, in short order, I found 3 cases in which
AP2, while improving, is still in no way equivalent to AP1. So I have a request of you at the end of this - but first:
Abrupt, unnecessary braking
Heading down the 60, under an overpass I went (one of many) and sure enough, abrupt braking for no other reason than the AP2 bug that's been with us since inception. Fortunately, the semi behind me was able to lock up briefly, I was able to accelerate quickly (less reaction time), and we all went about our business.
Automatic lane changes
Also found that "automatic" lane changes remained hit or miss - although as we've seen with AP2 over time, they're much less abrupt... more "natural", if you will. Problem is, they're not consistent. At all.
Speed limit sign failures --> TACC limit errors
When the limit changes from 70 or 65 to 55, AP1 would read that sign change and TACC/AS would reduce accordingly. Not the case still with AP2 *still*. Probably a dozen examples in just the first 400 miles of this trip.
As I've previously noted, neither AP1 (if camera blocked by big truck) nor AP2 (database errors aplenty) are perfect for speed limits - but a hybrid of the two approaches (let's call it AP3) would be really good (if camera reads sign then adjust else refer to correct database).
So the requests/questions, since I note you're in a different region: Do you get these speed limit sign errors as much as we do out here (CA/AZ/NV/UT and so forth), and/or the overpass behavior *with this latest version* where you are? In particular, I'm curious about the latter and here's why - the sun out here in the lower latitudes is decidedly bright so there's maximum contrast when heading under some of these light-colored (tan) overpasses. I'm not convinced that the problem is just the object, in other words.
The good news being that for Karpathy, 2 of these 3 remaining challenges (there are more than 3, but taking these for now) are clearly low-hanging fruit and you can't blame him for focusing on larger issues (such as recently mostly resolving the stopped objects far ahead issue). But this phantom braking thing seems as vexing today as when Elon referenced the dusk edge case on the 405 1.5-2 years ago now.
If you're not seeing this as much or at all, then that's good news, meaning that the current radar/cameras should eventually be able to handle it (since AP1 did and with less hardware). On the other hand, if it's happening up there as well... then it sounds like we have to wait and hope for a NN "aha" day.
Anyway, thanks for the video - good stuff.
