Self-driving cars, computer speech recognition and the collapse of the federal reserve system. Things that are going to perpetually happen next year since the inception of Hacker News.
Is "Linux on the Desktop next year" still a thing?
I have a feeling I'll be down voted to hell for this, but self driving cars always felt like going the complete wrong direction for me. Aside from small personal satisfaction to the few that will be able to afford them, how is revolving our infrastructure and culture around them any better than simply investing in public transportation by making it a more feasible option for people? I'm not in the US, and while the p…
There's also what's known as the "geometry" problem - 1 self driving car takes up as much space as 1 human driven car. Part of the problem is the general incompetency and mismanagement of US public transit construction -- the costs are insane, even when compared to "socialist" "high-cost" union-heavy Europe. This was a great read on why we get so little for our money: https://www.nytimes.com/2017/12/28/nyregion/new-y…

>when you consider how high road mortality is Except, depending upon your perspective, it really isn't most places. In the US it's about one fatality per 100 million miles driven and that includes driving under difficult conditions like snowstorms. People drive a lot so that still adds up to a lot of deaths per year. But the rate is not really all that high.
That rate is on the order of 1000x worse than airliners which was the comparison as that's the level of reliability people are expecting from self-driving cars. A self-driving car that's 100x worse than the airliner standard would still save 90% of all road fatalities. And yet saving 30k lives might still not be enough for people to accept such a lower standard compared to an airliner. https://en.wikipedia.org/wiki/T…
Why do you think this? It makes sense to me intuitively that people would be willing to accept more death causes by other people than more opaque and unfamiliar autonomous systems, but I haven't seen any hard data on this and am curious. Is this mentioned somewhere in the Wikipedia article that you linked or did you just share that to demonstrate the other number you mention?

I like Filip Piekniewski's take on this [0] - deep learning is appropriate for environments where the cost of mistakes is low (or the errors are reversible) and you're able to 'average them out'. Self-driving cars are absolutely not in that category. "If your errors are irreversible and you can't average them out, and your application is in open domain where there will never be a shortage of out of distribution sampl…
I think the best way to reduce those outlier cases in this phase is to just focus on self driving on the freeway. That's where it has the most value for me, taking over for the long boring hauls. On the freeway you minimize a lot of those wildcards like bikes and pedestrians, everyone is going about the same speed, and there are only a few places you can enter and exit. We don't need to jump all the way to self drivi…
So why hasn't this happened yet?
I believe this is because what we have here is not a technical problem, but primarily a regulatory and legal problem. If the political leadership of the NHTSA had the will to make highway self-driving happen, they could publish a draft safety and liability standard.
The technical problem here is that while shuttle and robotaxi systems can go slow enough as to make fatal accidents rare, as you said, the most consumer benefit potential is for a highway self-driving system that would not require active monitoring like Autopilot does.
The political/legal question is: when fatal accidents occur, who has the legal liability? If it's the manufacturer, then why would they accept the risk? If it's the driver, then who would actually go to sleep and let their robot potentially kill people? Especially given the problems that Tesla autopilot has with stationary targets in the road.
It's possible that the key innovation required here is not anything technical, but an insurance product that would allow the manufacturer to assume the liability, but be insured for damages. This insurance product would involve a deep technical evaluation of the self-driving system to get actuarial-level probabilities of mortality.
On the NHTSA website, there are many >50 self-driving test sites, but only 3 which are classified as "highway". The most common vehicle type is "shuttle". A full self-driving airport shuttle, with purpose-built road markings, makes a lot of sense as a goal achievable with today's technology, and is far more likely to kill people due to its controlled built environment and slow speeds. https://www.nhtsa.gov/automated-vehicles-safety/av-test-init...
Classic anti hype cycle. Won't age well.
How many nines of reliability do self driving cars need before they're safe? They have to operate in weather. Rain, snow, dark. They have to adapt to novel conditions. I put the self-driving car in the same category as the flying car and jet pack. This one just happens to have VC funding. I don't think we'll see these things for another decade, and when that next decade arrives we'll be saying the same. Another decad…

But that means it's not just a matter of building mass transit. First you have to build taller buildings.
And even then there are going to be places where it's just not happening. It doesn't matter how you change the zoning, nobody is going to build skyscrapers in Pine Bluffs, Wyoming.

But Elon says it's happening next year!
Oh it will happen, temporary. Until some really big accident happens in a situation where even a drunk driver wouldn't have messed up that way. After that self driving will be limited to situations like while you are in a traffic jam or limited to 30km/h and having it's own track or similar.
Outlier incidents shouldn't matter.
I think this article actually makes quite a fresh and interesting point, after the first few paragraphs that sound like stock self-driving skepticism. The author is pointing out that imagining self-driving cars of the same form-factor and niche as the human-driven cars today is a fallacy on par with a 1990s futurist imagining the internet as simply a way to send letters faster. The point is that changes to the techno…
Agree with your positive response. Missing from this conjecture is a synthesis with car and bike sharing. There will also be massive land use, zoning changes when there's 90% fewer personal cars. Unused capacity (parking, roads) freed up and repurposed. The role for autonomous driving for moving people (vs turking cargo) will look very different when our cities look more like medieval villas and college campuses. I s…
