My Tar line is fixed. It’s turning left so it’s off center only to show the line clearly in this frame. Very shiny but not fooled. This is improving fairly quickly.
I tested this patch of road several times yesterday with mixed results and I don't want to sugar coat anything here. Although it was the first evidence of a fix, later in the day the tree shadows crossed the road and again it got confused on where center of the road was. (Not a big deal here, it says in lane the whole time). It seemed to spook on a rare occasion with tree shadows (which is something that went away for me a long time ago). However, these variables around lighting are confluencing I think bc without the tree shadows it was fine (not a controlled experiment obviously). Keep in mind, the tar line looks like a road line and is almost perfectly straight and defined down the road center with room to travel either side. It's my # go to test on line recognition.
Speaking of lines, I would like to point out there was a story last night on a Model Y using Beta FSD and driving off the road. The vehicle appeared to turn into oncoming traffic, then the driver over corrected into the trees off to the right. What I also saw was the vehicle went perfectly straight, across the centerlines as the road curved to the right. The lines were solid double yellow and very clearly marked, so I suspect the driver may have tapped their brakes by accident as a much more likely explanation. These events or accidents will clearly get spun as FSD gets more real, but I can't say for sure what happened as the cars screen wasn't visible in the video.
For the folks who are first getting FSD Beta (and there could be many according to TeslaFi), please get used to the fast handling of Tesla steering and how to properly take over control. Overcorrection with all vehicle types is extremely common at higher speeds and it doesn't take much. This is why I prefer using the light tap method on the brakes to disengage before correcting as steering while braking sets up for very uneven tire traction and a + feedback loop to increase steering more.
I'm not sure I recommend the tap method for everyone bc you don't want to actually engage any brakes pads (and maybe using the stock is better in some ways, but this takes more time). I am used to it bc of my time on snow and ice. If you even slightly touch brakes on ice, it can set up a spin or break traction in a split second. And braking while turning is asking for trouble, but most drivers aren't skilled enough to even be aware of this physics. Oversteering happens on all vehicles and to many drivers, even the best.
Anyway, taking over control by forcing the wheel, in some cases and especially at higher speeds, could easily cause problems for an unskilled driver. If you think this sounds dangerous, then you're probably not ready for Beta. And by the same token, if you have an illusion that FSD will not cause accidents and be in the headlines with the competition shorting TSLA on every event, think again. A driving score of 99 or 100 does not test these advanced "hands-on" skills, nor does it consider your experience or even time using FSD - which IMHO should be a strong requirement for consideration into Beta (maybe they do this behind the scenes, IDK).
Given this, I'd be lying if I thought FSD was ready for full release this quarter, maybe Q1 TBD. Mostly because the average driver is going to make their usual driving errors and end up in a ditch and in the news while blaming it on FSD. The resistance on the steering wheel, which requires a bit more force for disengaging, adds to the overcorrection issue IMO. So tap the brakes then correct (if time allows), and I highly recommend when first trying it, practice disengaging a lot. Start at low speed and build up speed, skill, and confidence from there. Many do use the standard FSD on the freeways and there doesn't seem to be any growing concern there. But now we're getting into undivided territory, so be careful and keep it safe (speed etc).
