Yawn. Good lane markings, no rain/snow or other bad weather, perfect road surfaces. Just like all other self-driving demos. I'd like to see a demo like this on snow covered roads, with no lane markings visible. I think that would tell a lot more about the system's ability to deal with an imperfect world.

You lot are always so fixated on snow. Give it a decade or two and with global warming, the environment might meet us halfway on that one.

Doesnt climate change mean a higher probability of extreme events, and hence higher chances of severe winter storms/blizzard/snow?

I am out of my depth in terms of the topic we are discussing so I might be quite wrong.

> Handling yellow lights properly, involves us having to predict how long they will remain yellow for No. That isn't how yellow lights work in the US. If the light turns yellow and you have enough space/time to make a safe stop you do it. There's no need to predict the remaining time on yellow phase. We don't need robot cars bending these rules.

No. That's what the law says but not how you drive.

Suppose your 4 seconds from a yellow light traveling at a high speed. You can slam on your breaks and make a very abrupt stop, or you can cruise through that light and continue on your way.

If the light is about to turn red you should probably slam on your breaks, because you risk being t-boned in the intersection.

If you have time to get through the yellow light/before the cross light turns green, you should keep going because slamming on your breaks is mildly dangerous.

The law isn't nuanced enough to understand this, with good reason. You don't want to make a bad call about the safest action made in good faith illegal.

Most of these companies run closed-circuit tests (aka nerf-golf-carts) and 1000's of hours of simulation. In the end, the only test that matters is the real-test. Real speed (sensor/computation latency et al.), real sensor feeds (lighting et al.) and real car size (momentum et al.). Source: Am Controls engineer. There WILL be bugs and un-modellable sources of error. The real hedging in these situations is the safety…

"If the top speed is five miles per hour, so be it."

You are not really testing though. The whole point is to build a machine that can go the speed limit. You can test all you want at 5mph, but let me assure you, most of the real issues will show up when you go 45 in the real world.

What is the general view on Zoox's progress relative to other non-waymo playes. Such as Argo, Aurora and Cruise. There is the widely reported disengagement per mile, but most robotics people know it is just smoke and mirrors meant to make the regulators go away (disclosure, studied/researched robotics in grad school).

> There is the widely reported disengagement per mile, but most robotics people know it is just smoke and mirrors meant to make the regulators go away Are you saying that the numbers are inaccurately reported, or accurately reported but just don't tell the whole story?

Each company gets to decide for itself what qualifies as a disengagement and each event’s severity, and the formula used is a VERY closely guarded secret.

Interesting. Watch at 1/3 speed or so to see it in real time. (Self-driving car videos tend to be published sped up, so you don't see the mistakes.) The key part of this is, how well does it box everything in the environment? That's the first level of data reduction and the one that determines whether the vehicle hits things. It's doing OK. It's not perfect; it often misses short objects, such as dogs, backpacks on t…

> And as soon as you place too many restrictions, you no longer have a reliable transportation option. yes you do. There is a whole lot of driving that happens in perfect conditions. Think "Truck driving, on long highways". Replacing half of all truck drivers is still a trillion dollar industry. And for your robo taxi situation, you can simply only allow the robotaxis to run half of the time. Human drivers, can simpl…

Sure. Thats my point. And that is still very valuable.

Sure, eventually, when the machines and sensors and algorithms and so on are good enough. When the infrastructure can be rebuilt to accommodate them (e.g. Boring company tunnels for auto-trucking, sensors and comms in the roads and signage, &c.)

The rush to market is the whole problem. Not the ultimate concept.

I want a machine that can take my mother to her doctors appointment now that the dementia has gotten to the point where she shouldn't take the bus on her own anymore.

Let the experiences with the toy cars guide the incremental graceful adoption of faster machines.

> most of the real issues will show up when you go 45 in the real world.

Right! So don't go 45.

There is a different perspective that you could use (and I’m not necessarily advocating for it; hear me out): Human driven cars are dangerous to the tune of ~36,000 deaths per year. Every year without the implementation of full self driving we pay some large percentage of that number in lives. Self driving cars won’t make it out of the lab without real driving on real roads in real scenarios. Taking appropriate preca…

What about the nerf-golf-cart idea?

Speed is an important parameter: you can’t do freeway driving in a golf cart. IMO regular vehicles can be safe enough with appropriate supervision. It’s really once you get to the first runs without safety drivers where your backup goes away. Hopefully that will be only after your intervention rate is zero.
