No way to know if the AI FSD would have driven through or stopped. The discussion is not what would happen, but if it is a fair test comparison.

Assuming and not testing is failure regardless. I can’t tell you the result, but I would love to have seen it regardless of the final decision the Tesla made if it that was running HW4 using its AI on FSD.

Apparently I watched the wrong video for this answer. But Mark got the views he wanted from both of us for sure. Good stuff to think about and would love to see Tesla or someone else do extreme testing videos down the road that are good comps.
There is no doubt FSD would refuse to drive through such fog, I've experienced it firsthand. That's not the problem. The problem is a human driver will take over and continue driving in limited visibility, and given the vehicle can see much worse than the driver it won't brake for an obstacle. For the Nth time, FSD is irrelevant.

Whatever technology, no vehicle should be driven in those conditions. The only correct decision is not to. If FSD is the only actor refusing to do so, it is the only one performing properly, and legally.

I call bullshit on this too. Driving in fog, snowfall, rain all of which significantly impair visibility is standard for many areas. You slow down in relation to the actual visibility observed and continue driving. Yes, it can get bad to the point driving safely at any reasonable speed isn't possible, but FSD gives up way before such threshold.

Bad judgement is exactly why accidents happen in such conditions.

Remember, when we get the vaunted Robotaxis, it will have nothing else than FSD making those decisions. That is why we are told it will be a safer world.

What is test load? Some hitch standard in testing?

I am just saying it broke at ~10x of Tesla max tongue weight.

Exactly and the cybertruck exceeded this by almost 10x. His scenario during the video of saying hitting a pothole would transfer all the weight to the truck is complete bs. Again this looks to just be a reason to pump out videos and put negative energy in the direction of Tesla. Sad to see these well loved YouTube’s have become sell outs. At least that’s how this looks.

It is designed to tow an 11k trailer with 1,100 pound tongue weight which means the receiver is designed to withstand much more than 1,100 pounds. In other words, if it broke at 3,300 pounds, that would be a fail, not a "great! it handled 3x what it needs to".

That cannot be a valid argument a the Lexus is a custom vehicle that never had LIDAR in production vs a old HW3 version is suspect to begin with. If saying pressing a button to engage FSD which is a production feature on that this Tesla was capable of, is not needed or fair to compare. Then saying bolting on and wiring up 2025 brand new LIDAR system with custom coding to the communicate with the Lexus computer system, which was never on their production vehicle is even more unfair.
I think you’re missing the point. What he’s trying to communicate is the fact that LIDAR is a technology that can provide enhanced ability to an autonomous vehicle. Not this specific vehicle from Lexus but In general, On any vehicle that it was on, because it’s a mature technology, it’s out there now and CAN be used.

You are exactly correct. In the case of Jerry, he is full of shit or he didn’t understand what he was testing or how he was testing it. It was comical what he did and he lost so much credibility with his audience… Or at least with most of us.

It probably would not have made it a difference, which computer FSD was running on. Using just cameras It had limited ability to judge the depth of what it was looking at, certainly not enough to understand the difference between a painted road and a real road. That was the whole point of Mark‘s test and I don’t see why there is some thought that a faster computer could have figured this out better.

Technologies like LiDAR and RADAR provide enhanced situational awareness for autonomous vehicles compared to using cameras alone due to their complementary strengths:

- **LiDAR**: LiDAR uses laser pulses to create high-resolution 3D maps of the environment. It excels in providing precise object detection, size, and shape recognition, even in low-light conditions. This capability is critical for accurate navigation and obstacle avoidance[1][3][7].

- **Radar**: Radar uses electromagnetic waves to detect objects and measure their velocity and distance. It performs well in adverse weather conditions (e.g., fog, rain) where cameras and LiDAR may struggle, but it lacks the resolution of LiDAR[1][2].

- **Cameras**: Cameras mimic human vision, providing detailed color and texture information. However, they are limited by lighting conditions and cannot measure depth as effectively as LiDAR or radar[2][7].

By combining these technologies, autonomous vehicles achieve a robust multi-layered perception system. Cameras provide visual context, LiDAR ensures spatial precision, and radar enhances reliability in poor weather, collectively improving safety and navigation[1][3][7].

I used to think he must have some kind of engineering background or something. This video revealed to me that he has a very superficial knowledge of physics. At least Zach knows how to JerryRig something... Sort of. Sad state of affairs. The Roper video is a really sad story because he actually knows physics and science and understands how to set up an experiment. That was disappointing.

Both videos are purely for entertainment/making money. If you read anything more into that, you are mistaken.
There is no doubt that Lidar can do things camera vision alone can't. No one can argue that.
At the end of the day, which car/system would your prefer to have right now? At some point in the future I'm sure Tesla will add Lidar into their suite of sensors. Or something better.
Entertainment and clicks. That's all...

Per this Luminar dropped their sponsorship of Mark Robers video?

LoL if true
Dang that was fast, I guess they reached enough of his target audience to where they said ok we don’t need this no more.

should we feel bad?
