We in the US can't hide forever.

Forever is a long time.

Once FSD, we will make rules about the software that will have the effect of excluding Chinese companies. I seriously doubt that I'll see Chinese cars here in my lifetime.

Keep in mind, that $25k AUD is just $16600. And for that price, you're getting a real car with driver-assist features and a reasonable crash safety rating. The US car manufacturers are cooked.

I think it's a little early to make that claim. Jim Farley is definitely paying attention, for example. He drove a Chinese EV for a year, IIRC, and on many occasions talked bout the challenges of competing with them. I don't know what the real barrier to success will be, but I don't think it will be blindness. It may be difficulty competing on labor cost, but that's a good case for carefully applied tariffs to keep c…

US manufacturers are fine because the US has a long history of economic protectionism. These cars are effectively banned in the US due to tariffs which protect US automakers.

More importantly, the US will ban Chinese automation tech. Which is just fine by me. But I drive a 10 year old car.

Tariffs alone can't keep out cheap foreign products.

I am just some schmoe, but optics alone can be easily spoofed as any fan of the Wile E. Coyote has known for decades. [0] What's crazy to me is that anyone would think that anything short of ASI could take image based world understanding to true FSD. Tesla tried to replicate human response, ~"because humans only have eyes" but largely without even stereoscopic vision, ffs. [0] https://www.youtube.com/watch?v=IQJL3hts…

But optical illusions are much less of an issue because humans understand them and also suffer from them. That makes them easier to detect, easier to debug, and much less scary to the average driver. Sure, someone can put up a wall painted to look like a road, but we have about a century of experience that people will generally not do that. And if they do it's easy to understand why that was an issue, and both fixing…

> and punishing any malicious attempt at doing this would be swift

Is this a joke? Graffiti is now punishable and enforced by whom exactly? Who decides what constitutes an illegal image? How do you catch them? What if vision-only FSD sees a city-sanctioned brick building's mural as an actual sunset?

So you agree that all we need is AGI and human-equal sensors for Tesla-style FSD, but wait... plus some "swift" enforcement force for illegal murals? I love this, I have had heath issues recently, and I have not laughed this hard for a while. Thank you.

Hell, at the last "Tesla AI Day," Musk himself said ~"FSD basically requires AGI" - so he is well aware.

They don't have to die first. The company can avoid the expense by planning how not to kill people. If you charged car makers $20m per pedestrian killed by their cars regardless of fault you'd probably see much safer designs.

> They don't have to die first. The company can avoid the expense by planning how not to kill people. This is an extremely optimistic view on how companies work

I can think of one example where something similar works. The requirements from insurance companies on airline pilots are considerable tougher than the government ones because they are on the hook for ~$200m if they crash.

A big reason car companies don't worry much about killing pedestrians at the moment is it costs them ~$0.

everyone uses cellphone that transmit on the same frequency. they don't seem to cause interference. once enough lidar enters real word use. there will be regulation to make them work with each other.

Completely different problem domains. A mobile phone is interacting with a fixed point (i.e. cell tower) that coordinates and manages traffic across cell phones to minimize interference. LIDAR is like wifi, a commons that can be polluted at will by arbitrary actors. LIDAR has much more in common with ordinary radar (it is in the name, after all) and is similarly susceptible to interference.

No, LIDAR is relatively trivial to render immune to interference from other LIDARs. Look at how dozens of GPS satellites share the same frequency without stepping on each others' toes, for instance: https://en.wikipedia.org/wiki/Gold_code

Like GPS, LIDAR can be jammed or spoofed by intentional actors, of course. That part's not so easy to hand-wave away, but someone who wants to screw with road traffic will certainly have easier ways to do it.

The roof mount seems very practical, but it's a look that may turn off some buyers... buyers who care about looks. For SUVs, maybe it could be blended in with a roof air scoop, like on some off-road trucks. Or a light bar. Where is the LiDAR on the Atto 1? In the grille? How much worse is the field of view?

My impression is that Chinese consumer products haven't been hijacked by the "design above everything else" mindset. The priority is to make things work at scale. American product design is obsessed with appearance and finish. Products end up costing 3 times more and functionality is degraded.

i think over time tastes will change as people appreciate that function can define form, unlike the other way round

Lidars come down in price ~40x. https://cleantechnica.com/2025/03/20/lidars-wicked-cost-drop... Meanwhile visible light based tech is going up in price due to competing with ai on the extra gpu need while lidar gets the range/depth side of things for free. Ideally cars use both but if you had to choose one or the other for cost you’d be insane to choose vision over lidar. Musk made an ill timed decision to go vision…

Can lidar say what colour is traffic light?

Something I've seen noises about is time of flight systems for traffic. I think the idea is you can put those systems on traffic lights, cars, bicycles, and pedestrians and then cars can know where those things are.
