After less than a week on 12.3.4, I desperately want to roll back to 11.x. So far: CA-17 lane centering is way worse than before (or at least feels worse to me), and honestly, worse than pre-FSDb releases were. There's no way to engage TACC anymore (without parking the car and turning off...

Today, somebody told me that I'd left the trunk of my car open. It was in a work parking lot on a dry day, so no big deal, I guess, but it isn't the first time that has happened to me, and maybe not even the first time this year. It is just so easy to do if you get distracted while unloading...

So big that the model won't fit in HW4? 🤣

I guess that would at least partially explain why it took so long to get the transformer installed. PG&E is always slow for this sort of thing, but this one just seemed spectacularly so. 😁

I hope you're being sarcastic there. If you have no interior camera, it's incredibly easy to get a strike. Just drive through about two miles of inactive construction zones with both hands on the wheel, and pay attention to the road like you're supposed to instead of noticing the flashing on...

Any news on this site? There are six cars waiting to charge at Bernardo, and charging is peaking at just 120 kW, which means charging is way slower than usual, too.

Nobody said anything about turning it on and then tuning out. I'm talking about turning AP on because you have to do something that takes you away from complete concentration on the road for a few seconds. If Tesla wanted us to keep both hands on the wheel and eyes on the road every second...

My vehicle doesn't have a cabin camera. Also, that behavior is pure evil even on vehicles that do. 99% of the time, I engage AP precisely because I need to take my eyes away from the road to deal with something on the touchscreen. That is absolutely the worst possible time for it to be...

I've seen these problems with the new release on enough different vehicles (both with and without cameras) to conclude that this update is fundamentally flawed, and distracting to the point of being dangerous. NHTSA should force a recall of their recall.

The hands on wheel detection massively regressed in recent builds, thanks to a hopelessly botched NHTSA recall. It now has a 50/50 chance of claiming that I don't have my hands on the wheel, with audible warning, with no prior visible warning, about a second after engaging autopilot. I...

This new recall update has made FSD AutoPilot basically unusable. It has a 50/50 chance of triggering a hands-on-wheel audible warning within one second after engaging AutoPilot, which results in me immediately disengaging AutoPilot to avoid the risk of getting a strike. Audible nags trigger...

Presumably because it is no longer a beta strike, but an FSD strike. The new scheme, where FSD strikes accumulate until you can't use FSD for a week, is seriously sketch unless they start automatically removing old strikes on a schedule.

There's some discussion here: https://teslamotorsclub.com/tmc/threads/ap1-ap3-theoretical.190444/ I could swear I remember there being a thread where someone actually did it and commented on what a huge pain in the backside it was, and that it totally wasn't worth doing, but I can't find it...

28 weeks is (quite) a few. 🤣

Yeah, I gave up trying to report problems with Tesla routing. When I drive from work to another place a few blocks away, it tries to make me do an illegal left turn. If I refuse to go down the road that would lead me to that illegal left turn, it tries to make me make a left turn and an...

All that does is encourage people to drive worse than usual right before they go on vacation. I predict an uptick in FSD crashes right before Christmas. 🤣

The intermittent wipers on my Model X (2017) also stopped working some time since the last couple of months, and is still nonfunctional in the update pushed last night. This appears to be a defect in FSD beta. Auto wipers toggle makes no difference. As nonfunctional wipers are a safety...

It was amazingly common with highway autopilot, too. It has gotten a lot better, but it is still reacting, just not as strongly. By the time it gets around to reacting, it shouldn't even be reacting anymore. I can't imagine the pipeline latency still being measured in seconds in HW3, so I...

I used the wrong word. I actually meant energy (Wh/kg and Wh/L). But it is possible that the numbers I found when I looked it up were wrong, or that I misread grams as kilograms or kilowatts as watts or... no idea. :) Yes, the discharge curve is something that has to be dealt with, but it...

Supercapacitors can be several times more dense than lithium-ion batteries (both in terms of energy per kg and per liter), and you could add lots of armor around supercapacitor packs with that much weight and space savings. The main problem with capacitors is self-discharge. For...

Now that Tesla has eliminated the standard range Model X, they seriously need to rethink charging $2,000 for an interior color change. That tiny little cost pushes the car over the $80,000 cap for getting a federal tax credit, which means it costs almost ten grand just to change the color of...

That's not really true. RADAR detects reflections without regard to whether the reflection comes from something moving or stationary. The "doppler" part just refers to the fact that it measures the frequency of the reflection and can use that to determine the speed of the object relative to...

In this case, it was, though. It wasn't just Musk saying it. Their RADAR was low-resolution hardware designed for emergency braking and not much else. It had imprecision that was severe enough to make guard rails appear to be within the lane bounds under a lot of circumstances, and removing...

I have my doubts that heaters are a complete solution. There's only so much that a heating element can do when the outside of the bumper is being super-cooled by traveling through 5-degree Fahrenheit air at 65 MPH, and then gets hit by a hunk of packed snow thrown up by the wheel of a passing...

I'll grant you rain, but in frozen weather, your bumper quickly ends up with such a thick layer of ice that RADAR becomes useless, and if not properly ignored, can actually do more harm than good. And what do you do when (not if) RADAR fails? Do you refuse to drive until someone clears the ice...

Out of my interventions that seemed like safety problems initially, nearly all of them actually weren't safety problems with the benefit of hindsight, though I have had to intervene to keep it from trying to pass a long line of stopped cars at a stop sign a few times, and that's kind of bad. 😁...

Automotive RADAR absolutely gets reflections from rain. The noise from the rain itself, if necessary, can be filtered out by a clutter suppression algorithm (*), though I'm not sure if they actually bother. Also water sitting on the bumper causes attenuation, and snow or ice on the bumper can...

I think it is literally just this. Lane planning is at least 70% of what's wrong with FSD beta, and possibly as much as 90%. The rest of the problems I've seen, with only a few exceptions, involve incorrect lane perception, where it freaks out and beeps about a stopped vehicle that is parked...

Perhaps they should just call it "laudable self driving (LSD)"?

I was attentive to the road (and have no camera either way). Perfect weather, medium traffic, mid-afternoon sun, second lane from the right.

I just saw a huge regression in the hands-on-wheel detection behavior. With no change in behavior, I got a barrage of nags one right after the next over about a one-minute period, culminating in an FSD strike. My hands were on the wheel the whole time, and I responded to every nag that I saw...

I'm suddenly feeling really lucky to have just replaced the 12V battery in my late-2017 for the first time after ~5.5 years. 😁

One difference is that there are no real technological reasons preventing us from colonize Mars right now (or within single-digit years). Yes, we'd like more powerful rockets so we can send bigger loads to Mars, but the lack of such hardware isn't a show-stopper block-ship bug. We could build...

It also seems possible that the human driver doing so is the reason why the car thought it should, and that a human driver might make the same mistake if not fully paying attention.

Why is a critical component that is potentially exposed to water made out of a material that can rust in the first place?

In the software industry, we frequently use something called "feature flags", wherein we can turn on or off specific features. I know for a fact that Tesla uses these, or at least did use them at one time, because there was a post by GreenTheOnly that described some of those flags, including...

I don't get 11.4.4. The first few days, at a time when I needed it most (on the way to the hospital behind the ambulance when my father passed away), and for a couple of days thereafter, it was way better than any previous version, with almost zero disengagements. Then, over the weekend, it...

Which is sad, because it was coming soon two years ago. https://www.cnet.com/roadshow/news/elon-musk-tesla-vision-features/

According to this, HW4 is likely either a 4nm or 7nm TSMC process. HW3 used a 14nm process.

Who said anything about additional cameras? The proposal was to replace the cluster of three front-facing cameras (wide, normal, narrow) with two front-facing cameras pointed like X-Y microphones, where the one on the right points left and the one on the left points right. It would actually...

And would be trivial to retrofit into HW3 cars as well.

You forgot to multiply by 5. That $10M is still after amortizing the labor cost across five updates, just like the $40 million was. The top of their pay scale for techs is somewhere around $40 per hour, but the average is considerably less than that. And you can't consider opportunity cost...

It depends on how many more times they have to replace it before it actually works. If doing a compatibility rework adds an extra $100 in (actual) labor costs, but you do that only once, times 2 million cars, that's a $200 million cost. If they can't pull off FSD according to spec until HW8...

It's not just a case of changing the board layout to accommodate connectors here. If I understand correctly, HW4 is a single, unified computer that replaces both the FSD computer and the MCU computer. So they would have two choices: Either design a new board from scratch that removes the MCU...

Worse, if you have multiple Bluetooth devices and get out of the car to plug in at the Supercharger, even without closing the door, it kicks out whatever Bluetooth device is currently connected and switches back to the primary Bluetooth device. It is utterly annoying.

HW2.5 was released in August 2017, and that's consistent with what I remember from back then. MCU2 was March 2018, HW3 was March 2019.

It would be surprising if any remanufactured battery had the range and energy capacity of a battery that has only 4,000 miles on it. But the energy capacity is pretty closely tied to the cycle count, so...

I would definitely push back on that. Replacing failed parts with reconditioned parts is usually a reasonable thing, but in this case, batteries are wear items, and approximately 100% of reconditioned batteries will have much, much higher mileage than the battery that you're losing. In effect...

Yeah, sometimes I probably overthink things. 😁

I'm not an AI expert by any means, but based on my limited understanding, that's actually not encapsulated in #1, which was: Obviously the simulations don't have enough data to cover all of the interesting edge cases that people are seeing, or else we wouldn't be seeing them. We don't know if...
