This is tangentially related, and something I have wondered, so I will ask it here. Does anyone know how self driving cars will react to attempts by law enforcement officers to pull over the vehicle?

They will pull over.

One would hope! lol. But seriously, how do you know this? Just curious.

Waymo seems to be the only question mark in my mind making me doubt my bet that we're a decade or more away from usable self-driving cars. If Waymo has truly solved the problem while everybody else is just trying to catch up and/or bluffing, I guess I wouldn't be that surprised. Edited to add: The reason is that they've apparently ordered 10's of thousands of these cars. Can they really use that many only in good-wea…

I'm sure Waymo will make a lot of progress with their massive investment but using SV money as an indicator for a project's ultimate success seems unwise at this point.

I think the real question is whether the big investors in self-driving cars will make progress creating virtual rails for their vehicles, e.g. roads where we can keep pedestrians out.

I'm continually astounded by the Tesla hasbara:

"Tesla and a host of other imitators already sell a limited form of Autopilot"

Imitators? You mean GM, Mercedes and VAG that have had these systems for longer than Tesla are just bad copies of the glorious Tesla autopilot?

Unreal.

> Imho, companies need to collaborate on certain aspects like perception instead of competing. I also work on self-driving cars. Why would I share technological innovations with another company?

It isn't unheard of in this space for safety considerations: https://priceonomics.com/volvo-gave-away-the-most-important-...

But a safety belt doesn't drive the car for you.

This has been hanging out there for a while it's just that it never got much mainstream press. I wonder what it is specifically about the concept of "AI" that makes it so prone to the magical thinking that drives these boom-bust cycles. "I tell adult audiences not to expect it in their lifetimes. And I say the same thing to students" "Merely dealing with lighting conditions, weather conditions, and traffic conditions…

'It may be a hundred years before a computer beats humans at Go — maybe even longer,'' Piet Hut, an astrophysicist at the Institute for Advanced Study in New Jersey, told the NYT in 1997. ''If a reasonably intelligent person learned to play Go, in a few months he could beat all existing computer programs. You don't have to be a Kasparov.''

Another attack surface for self-driving cars

As long as software is composed of primitive language derived statements and "functional" logic (IF, WHEN, WHILE, DO, GOTO, etc...) AI will remain a fantasy.

This is hard to parse. All software that can be represented as if and goto (and some sort of assignment i suppose)? when, while and do are just if and goto. alpha go is all just if and goto. I'm not sure what you're looking for or alluding to. Is there some other operation that isn't just if and goto? because i think any function you come up with, i can just make a big table of inputs that result in specific outputs.…

I believe what he's saying is that we don't "think" in if/then statements. So true AI will never be intelligent-like if you judge intelligence as thinking like us.

How much better than human drivers do self-driving cars have to be to succeed? If you take a metric like fatalities or damage per mile I'm guessing we ask our robots to be much better than humans, even though it doesn't really make sense. Over time the differential will come down but a better intermediate strategy would be to keep humans away from robot cars until collision avoidance techniques improve substantially.

The crashes that the article claims came from edge-cases that the engineers didn't account for weren't, in fact, edge-cases. The Tesla crashes are due to the way Tesla's system works, it doesn't recognize stationary hazards. Similarly Uber's system failed to brake for a hazard that it could clearly see. That's not an edge-case, it doesn't have to know that the object is a woman pushing a bicycle. It's a solid object…

Edges cases are what really matters in this case! Isn't there a saying that 80% of the code is written to handle 20% of the cases?

but the problem is that you need to properly resolve base cases before starting on edge cases. The fact that base case scenarios are not properly solved hints at major problems in execution.

Waymo has also ordered 20k Jaguar I-paces. Rumour is they have invested about 11 billion in R&d so far, and I'm crudely estimating the cost of their 80k upcoming robotaxis to be around 12 billion. Alphabet is committed. Waymo estimates about 50 trips per day will be served per vehicle. At that rate, 80k robotaxis is enough to displace most of the taxi/rideshare services in the southwestern United States, though I'm n…

In this scenario there's no moat for Lyft/Uber either. If Waymo can meet demand, they'll be able to undercut ride sharing prices so deeply that most consumers will switch overnight. Banks will be falling over themselves to provide the massive credit they'll need to bankroll the expansion.

> they'll be able to undercut ride sharing prices

Why?

I see comments like this constantly. But does anyone ever do even a basic spreadsheet to explain the unit economics of this argument?

Low skilled people who can drive are pretty cheap and plentiful. Even if self-driving tech is flawless (spoiler: it's not and won't be soon) it still only replaces part of their responsibilities. Someone will still have to clean the cars for example. Presumably there will be some required level of human monitoring, etc.

Conversely, capital and highly reliable technology isn't free. You can calculate pretty easily the rate at which it's profitable to substitute technology for labor, this is a trade-off we've literally been making for centuries.

One one side you have plentiful cheap low skilled labor. On the other you have lasers, fast computers, graphics cards, cameras, and the associated programming inspection and maintenance costs.

Why do we think the latter side is going to be cheaper in anything remotely like the near term?
