Does the Tesla “Full Self Driving” Approach Have a “See-Saw Problem”?

Tesla followers are actually nicely conscious of Tesla’s method to “full self driving,” however I’ll present a brilliant fast abstract right here simply to ensure all readers are on the identical web page. Mainly, in the meanwhile, Tesla drivers in North America who purchased the “Full Self Driving” package deal and handed a Security Rating check have a beta model of door-to-door Tesla Autopilot/Full Self Driving activated of their automobiles. If I put a vacation spot in my Tesla Mannequin 3’s navigation as I’m leaving the driveway, my automotive will drive there by itself — in concept. It’s not near excellent, and drivers should vigilantly monitor the automotive because it drives so as to intervene each time crucial, nevertheless it now has broad functionality to drive “anyplace.” Once we drive round with Full Self Driving (FSD) on, if there’s an issue (both a disengagement or if the driving force faucets somewhat video icon to ship a video clip of latest driving to Tesla HQ), members of the Tesla Autopilot workforce appears to be like on the clip. If wanted, they re-drive the state of affairs in a simulation program and reply to the difficulty within the appropriate approach so as to train the Tesla software program how you can deal with that state of affairs.

I obtained entry to FSD Beta a number of months in the past (early October 2021). Once I obtained it, I used to be fairly stunned at how dangerous it was in my space. I used to be stunned since 1) I had seen lots of hype about how good it was (together with from Elon Musk and different folks I typically belief in the case of Tesla issues) and a pair of) I reside in a very easy space for driving (a Florida suburb). Once I began utilizing FSD Beta, I used to be simply not anticipating to see that it had vital issues with fundamental driving duties in a driving setting that’s about as straightforward because it will get. Nonetheless, I retained some hope that it might be taught from its errors and from the suggestions I used to be sending to Tesla HQ. Certainly, it couldn’t be exhausting to appropriate some evident issues and every replace could be higher and higher.

I’ve seen some enhancements since then. Nevertheless, updates have additionally introduced new issues! I didn’t count on that, at the very least to not the diploma I’ve seen it. I’ve contemplated over this for some time. Mainly, I’ve been making an attempt to know explanation why Tesla FSD isn’t nearly as good as I’d hoped it might be by now, and why it typically will get considerably worse. One potential challenge is what I’m calling the “see-saw downside.” If my concept is appropriate to any notable diploma, it might be a important fault in Tesla’s method to widespread, generalized self driving.

My concern is that as Tesla corrects flagged points and uploads new software program to Tesla buyer automobiles, these corrections create points elsewhere. In different phrases, they’re simply taking part in software program see-saw. I’m not saying that is positively occurring, however whether it is, then Tesla’s AI method might not be enough for this function with out vital modifications.

As I’ve been driving for months interested by what the automotive sees and the way the FSD software program responds, I’ve come to understand that there’s rather more nuance to driving than we sometimes notice. There are all types of little cues, variations within the roadway, variations in visitors movement and visibility, animal exercise, and human conduct that we discover after which select to both ignore or reply to — and typically we watch it intently for a bit whereas we resolve between these two choices as a result of we all know that small variations within the state of affairs can change how we should always reply. The issues that make us react or not are extensive ranging and may be actually exhausting to place into bins. Or, let’s put it one other approach: for those who put one thing right into a field (“act like this right here”) based mostly on how an individual ought to reply in a single drive, it’s inevitable that the rule used for that won’t apply accurately in an analogous however completely different state of affairs, and can result in the automotive doing what it shouldn’t (e.g., reacting as an alternative of ignoring).

Let me attempt to put this into extra concrete, clearer phrases. The most typical route I drive is a 10-minute route from my house to my children’ faculty. It’s a easy drive on principally residential roads with extensive lanes and average visitors. Again earlier than I had FSD Beta, I might use Tesla Autopilot (adaptive cruise management, lane preserving, and automated lane modifications) on most of this route and it might flawlessly do its job. The one motive for not utilizing it on nearly the complete drive was the issue of potholes and a few particularly bumpy sections the place it’s good to drive in an uncentered approach within the lane so as to not make everybody’s tooth chatter (solely a slight exaggeration). In truth, apart from these consolation & tire safety points, the one motive it couldn’t drive the entire approach is that it couldn’t make turns. Once I handed the Security Rating check and obtained FSD Beta, that additionally meant dropping using radar and counting on “imaginative and prescient solely.” The brand new and “improved” FSD software program might hypothetically do the identical activity however might make these turns. Nevertheless, FSD Beta utilizing imaginative and prescient solely (no radar) had points — primarily, lots of phantom braking. As a brand new model of FSD Beta would roll out and a few Tesla fanatics would rave about how significantly better it was, I’d eagerly improve and check out it out. Generally it improved a bit. Different instances it obtained a lot worse. Lately, it engaged in some loopy phantom swerving and extra phantom braking, seemingly responding to completely different cues than it responded to in earlier drives. That is the form of factor that gave me the hunch that corrections for points recognized elsewhere by different Tesla FSD Beta customers had led to overreactions in a few of my driving situations.

In brief, my hunch is that too generalized of a system — at the very least, one based mostly on imaginative and prescient solely — can’t reply appropriately to the various completely different situations drivers run throughout each day. And fixing for every little set off or false set off in simply the correct approach entails approach an excessive amount of nuance. Instructing software program to brake for “ABCDEFGY” however not for “ABCDEFGH” is maybe straightforward sufficient, however educating it to reply accurately to 100,000 completely different nuanced variations of that’s impractical and unrealistic.

Maybe Tesla FSD can get to a stage of acceptable security with this method nonetheless. (I’m skeptical at this level.) Nevertheless, as a number of customers have identified, the purpose must be for the drives to be easy and nice. With this method, it’s exhausting to think about that Tesla can minimize the phantom braking and phantom swerving sufficient to make the driving expertise “passable.” If it might probably, I can be fortunately stunned and one of many first to have fun it.

I do know it is a quite simple evaluation, and the “see-saw downside” is only a concept that’s based mostly on person expertise and fairly restricted understanding of what Tesla’s AI workforce is doing, so I’m under no circumstances saying that it is a certainty. Nevertheless, it appears extra logical to me at this cut-off date than assuming that Tesla goes to adequately train the AI to drive nicely throughout the various barely completely different environments and situations the place it has FSD Beta deployed. If I’m lacking one thing or have a clearly defective concept right here, be happy to roast me down within the feedback under.
