Not exactly. The idea is that if you need vision to work when the map is wrong, then that means the car can do it without maps. So if you trust that a map-using AV can safely drive when the maps are wrong, then you should trust the car when driving anywhere without maps (since maps can be wrong anywhere anytime because of construction, a parade, an accident, a cone, etc.)
That's the assumption I'm not convinced of. Waymo's working robotaxi is too restricted to be convincing. Case in point is that Waymo taxi rider who got stuck because of a few cones:
Again, maybe it's regional, but FSD beta does great on right turns for me IF the cross traffic is controlled (e.g. - traffic coming from the left has a stop sigh, red light, etc.) or IF turning right at an intersection where we have a green light (right green or straight green). But yes, it's jerky/super hesitant/not good enough when turning right at a stop sign onto a large/fast street.
Nobody ever said Tesla is like other legacy automakers.Other companies aren’t selling their solution for 10k (soon 12k).
Yes, if something is not required then it is not needed.A human can see and adjust quickly when a lane that used to be able to go straight is now a turn only lane. A human can adjust if the road they need to turn onto is blocked off because of an accident. But if a FSD car requires that kind of exact predetermined map to operate it would not be able handle these kind of everyday situations. And if the FSD car doesn't require such maps and can still drive competently and safely like a human could even when the predetermined map is wrong then you don't need such exact predetermined maps at all.
That was one instance out of millions of miles and it was caused by a remote operator giving the car bad advice. Waymo handles cones just fine all the time.
Really, its a computer algorithm, if it happens once, it'll happen again, and again, and again…

Regressions are disappointing. All software teams I know of build giant regression test suites and every new build is run on all the logs or simulations of prior situations to minimize regressions. This is harder if you are using neural nets, and also if you are using a fleet of customer cars which don't upload a complete log of everything from a previous failure event. Tesla claims their simulator is great, and perhaps it is, but it doesn't seem to find these regressions you are reporting. That will be a bigger issue if it goes into production.@bradtem
I appreciated your article. And also cool to see your presence here! TBH when I started to read the article, I was preparing myself to become defensive against the typical shallow FUD-like articles. But I read through all of it and agreed with your assessments. I think if I had not been part of FSD beta since 10.2, I may have had more optimism for FSD and likely would have disagreed more with your piece.
I do see incremental improvements since 10.2, but there are also lots of regressions. Overall, while I'm happy that FSD is improving, it's improving at quite a slow rate. Especially when things that most users expect to be easy (right turns at residential T intersections, for example) continue to be a struggle.
Musk would have us believe that the AI will be improving at an exponential rate, and early on in the curve, the improvements seem linear, and we has humans have a tendency to think linearly. So any day now, we might hit that inflection point where progress becomes noticeably faster. But from 10.2 to 10.8, I've yet to feel any acceleration in improvement, so for now, I'm going to extrapolate linearly and assume FSD won't approach L4 for at least 2-5 years.
AI Day did mention the idea of crowdsourcing mapping. It might not be HD mapping, but the idea that a particular intersection's rules can be refined and remembered through multiple cars' vision data seemed promising. Here in New England / northeastern USA, there are so many wacky intersections that don't have an analog anywhere else in the country. Drivers new to the area are regularly honked at for not knowing how to navigate these areas. I have no expectation that FSD could ever do better without some sort of memory of how the intersection works.
This is one thing that gets me. What engineering approach shuts the doors so firmly on any possible solution? If you are going to back one horse like vision, then surely step one would be to have a perfectly stitched and processed 360 image that you can treat as a single integrated data source? As for other sensors, just don't mention them until there is a compelling reason to give them consideration.like not using LIDAR (and radar) and not using detailed maps. That makes it hard to back off from them.
HD maps are a crutch to deal with the current limited ability to perceive and process what the car perceives. Clearly it makes more since to improve the cars ability to perceive. How can a car that relies on networked HD maps truely be level 5?
Crutches serve a purpose though.
One purpose HD maps serve is a way to trigger additional learning when the perception is wrong. For example snow plowing removed lane divider dots on a multiple lane road near me. FSD Beta doesn't recognize it as two lanes, and centers itself in a way where its a bit in the other lane.
HD Maps would tell it that there are actually 2 lanes there.
appear to be working on FSD but wants to do so in a way that minimizes costs while still being plausibly believable.
The situation I was describing involved no snow as all the snow had melted.This is actually a really good argument for why you DON'T want to rely on HD maps.
I used to live in a state where snow plowing would routinely turn 2 lanes into 1 and in such situations there's not a lot of room between the snow banks and it would be unsafe to try to squeeze 2 lanes into that space especially in a winter snowy situation where you should leave MORE space between cars.
Yes, if something is not required then it is not needed.
No human can “drive competently and safely like a human” on their first drive.
We don’t want our cars to drive like humans.
We can’t download maps into human brains — they need to generate those through experience. We want our cars to drive safely immediately after we have received the update! Why not give them every advantage (like the best maps) to make up for the lack of experience they have?
To save processing time, humans are constantly comparing the present with the past - if something appears exactly as it was in the past why re-invent the wheel? Computing resources and time are limited. Instead of generating their own memories, cars can have the up-to-date collective memory of the fleet (and cartographers).
Would some students perform better on their practical driving tests if they studied detailed maps of the route and which maneuvers would be required BEFORE the test? Clearly not all students need such maps, but for some it might be the difference between passing or failing. If such maps aren’t always available to humans, we want them to fail. But don’t we want the cars to always succeed, even on the very first drive?
You call routinely going 45+ mph low speeds?Waymo doesn't have true FSD. It only works at low speeds and only in specific carefully curated areas. Sure it's better than what Tesla has but that's not true FSD in my book.
Streets actually rarely change. Nevertheless crowd-sourcing solves this problem. Its already happening with tech like REM map that Mobileye has already deployed.And what I'm telling you is that that's nonsense. Streets are constantly changing. You can't just map them once and expect them to remain the same forever!
There are hundreds of videos of Waymo driving with no driver that are freely available. Have you even bothered to watch any and check out the speeds for yourself?You do understand that what they wrote in a design document and what they allow the car to do in real life are two entirely different things, don't you?
All self driving cars operate like this unless they would crash immediately if all they relied on was their map.That doesn't say that it can operate without the maps when they're wrong.
My opinion is that Tesla (and Musk) already know they've lost the FSD race and any actions they take now are to lower costs while at the same time balancing the need to minimize the risk of legal action from those who made past buying decisions based on seemingly false or grossly misleading prior statements.
In other words Tesla still needs to appear to be working on FSD but wants to do so in a way that minimizes costs while still being plausibly believable.
Tesla is using maps, just not HD maps. Your Tesla knows a stop sign is coming up before the car can even see it (if the map is up to date). Perhaps not addressing your wider point, but at least in the case of someone stealing a stop sign, that’s pretty dangerous even in a world of just human drivers, since some will remember/know there’s supposed to be one there, and some will not (newcomers, infrequent drivers of the area, etc.)The situation I was describing involved no snow as all the snow had melted.
It does present an interesting case where the human mind easily handles the task.
When there is no snow we use internal maps to know there is supposed to be two lanes there, and its not just a single lane. In my observation about 95% of the drivers knew there was two lanes and kept to their sides, and there was only one or two people who seem confused. This was over about a week of going through that area.
When there is snow banks we ignore the internal maps, and we normally form a single lane with maybe one or two idiots that try to squeeze by occasionally.
Essentially what I'm getting at is the equivalent of HD maps exist for humans. We're often driving over the same road over, and over so we know what changes. If someone steals a stop sign we know we're still supposed to stop.
