In what sense does Tesla use their own chips?

Let me Google that for you?

They have no fabs. They're using nvidia chips on server side last I checked, and what tsmc thei own design for in car? Those aren't cheap anyway. The markup on nvidia chips is high, but it's not _that_ high.

My present car is 18 years (and, other than 2 non functioning buttons that I decided I didn’t want to pay to replace), working perfectly fine. And, I should say, I’m a terrible owner. This car had (at most) 10 maintenance checks (and oil changes) in its life. Emphasis in “at most”. I intend to buy a new one in about 3 years and there’s no chance in hell I’m going for something shiny that breaks after 5 years like thi…

Chinese cars have come a long way, most of them have better quality than any European maker. And almost of them come with very long warranty periods as well. Go take a test drive in one to find out what you been missing out on.

> Chinese cars have come a long way, most of them have better quality than any European maker.

That's just not true. They absolutely don't. There's no chance in hell most (or any for that matter) Chinese carmaker has better quality than a Volvo, or a BMW, or a Mercedes or an Audi, or, etc, etc

I wonder if ubiquity doesn’t effect the lidar performance? Wouldn’t the systems see each other’s laser projections if there are multiple cars close to each other? Also is LIDAR immune to other issues like bright 3rd party sources? At least on iPhone I’m having faceid performance degradation. Also, I suspect other issues like thin or transparent objects net being detected. With vision you rely on external source or fl…

There are regular 100+ car pileups in the central California valley due to fog. Cars crash in a lot of situations because the driver simply can't see. We need something better than vision to avoid these kinds of accidents. Coordinated cars won't work unless all cars are built the same and all maintained 100% the same and regularly inspected. You can't have a car driving 2 inches from the car in front, if it can't sto…

A combination of cameras, lidar, ridar, ultrasonic fused together have a strong sense of perception since they fill in each other's gaps. (short, long, different spectrums of electro-magnetic spectrum / sound).

The good news is they're all commodity hardware prices now.

Tesla removing radar and parking ultrasonic sensors was a self own. Computer vision inference is pretty bad when all the camera sees is a while wall when backing up.

Fog - Radar will perceive the car. Multi car crash, long range radar picks it up.

Bright glare from sun, lidar picks it up. Lidar misses something, camera picks it up.

Waymo has the correct approach on perception. Jam with sensor so they have superhuman vision of environment around.

Both HW versions have problems (and I have both). FSD has been "really good since VVV" for the last 6 major versions or so. > Red hands of death would be sunglare due to your windshield not being clean. I haven't had red hands since 14 came out. My windshield is completely normal. Not unusually dirty or anything. It's also Seattle. What is the "sunglare"?

> FSD has been "really good since VVV" These are influencers who have a stake in Tesla. The general consensus from the regular users is that it is really good starting at FSD 14. It's the first version that finally feels complete. I have 5000 miles on FSD 14 with no disengagements. 99% of my driving is FSD. I couldn't say that for any other version. Even my wife has 85% of her driving on FSD and she hated it before.…

> These are influencers who have a stake in Tesla.

I've seen it on multiple forums. Just like a broken record.

> If it's never been cleaned from the inside, it's a good chance it's not.

The camera is clean. I can see that on the dashcam records. And if the system is so fragile that a bit of dust kills it, then it's not good.

The issue with the red-hands-of-death is caused by the forward collision warning, the road there curves and slopes up, so the car gets confused and interprets the car in front as if it's on a collision course. This happens even during manual driving, btw. False FCWs are a common problem, if you check forums, and people are annoyed because it affects their safety score used for Tesla Insurance.

FSD got better than it was 4 years ago. But it's still _nowhere_ near Waymo. You absolutely can not just sit back and snooze while it's driving, you constantly have to be on guard.

Being literally the worst human rights violator makes it easy to be cheap https://www.amnesty.org/en/latest/news/2024/10/human-rights-...

The graph has this group which includes mostly Eastern car manufacturer: > No demonstration of alignment (0-22 points) What does "no demonstration of alignment" mean in this context? Eastern companies often don't proactively demonstrate compliance beyond what's legally required, especially to Western NGOs. Does this lack of demonstration actually prove they're violating human rights?

I've struggled with this over the years, but think we can call it at this point: Waymo is definitely better. Just too much real world data. (i.e. scaled paid service, no drivers, multiple cities, for 1 year+)

We being who? What is your evidence it's better? The fact all the cars stopped moving when the power went out? The fact they cost WayMore? Show the evidence for your claims. And they have remote operators as proven by the power outage.

Waymo operates without a safety driver. That's a slam dunk right there.

No, some edge case that made the cars fail safely during a power outage doesn't compare. If that's the best you can come up with, you've got nothing.

Show the cost differences and do the math then come back to us before you can suggest what decisions were ill timed. Otherwise it's just armchair engineering.

I'd love to take on this challenge: the article they linked shows the cost add for LIDAR (+$130) -- -- but I'm not sure how to get data on ex. how much Tesla is charged for a Nvidia whatever or what compute Waymo has -- My personal take is Waymo uses cameras too so maybe we have to assume the worst case, +full cost of lidar / +$130

  >I'd love to take on this challenge: the article they linked shows the cost add for LIDAR (+$130)
The article claims that, but when you actually try to follow the source it fails the fact check.

It wasn't ill timed. Any sane leader would understand both size and cost of tech always comes down rather quickly over time. He's just refused to accept having lidar uglify his cars or wait for it to get smaller. He instead fabricates about humans don't have lidars so cars shouldn't have them and sold "no lidars on Teslas" as an advantage instead of the opposite and refuses to accept the truth due to needing to feed…

That always struck me as a weak argument. Humans don't have wheels, so maybe he should have designed cars without wheels too.

That strikes me as a weak argument. We have vehicles with legs, but wheels are just better, practically speaking.

The argument is that humans provide a proof-of-concept that vision + neural net can drive a car, because (for some reason) some people doubt this is possible. However there's no need for a "proof of concept" that mechanical legs can be built, because everyone already know that building mechanical legs is possible.

What do you mean by proportion? They are different data sources, and their usage is determined by system design. eg A driving decision system needs to know object distances AND traffic light colours. It doesn't particularly need to know the source of either. You could have a camera-only system that accurately determines colour and fuzzy-determines distance. Or you could have a LIDAR-only system that accurately determ…

Sounds like a solved problem and you can buy a solution with a perfect accuracy?

Is there a point you're trying to make?

Because it really feels like you're just JAQing off, either to come to some "gotcha" moment or a pseudo-intellectual exercise. In either case, the questions feel bad faith.
