I'd like to see Waymo have a few of their Drivers do some sim racing training and then compete in some live events. It wouldn't matter much to me if they were fast at all, I'd like to see them go into the rookie classes in various games and see how they avoid crashes from inexperienced players. I believe that it would be the ultimate "shitty drivers vs. AI" test.

Racing and street driving are completely different. Racing involves detailed knowledge of vehicle dynamics and grip. Street driving is mainly obstacle recognition and avoidance. No waymo ever operates anywhere close to the limit of grip, which is where you are all the time when racing.

It is great being able to generate a much larger universe of possibilities than what they can gather from real world data collection, but I'd be curious to learn how they check that the generated data is a superset of the possibility-space seen in the real world (e.g. confirm that their models closely match what is seen in the real world too)

IIUC, there's a confusion of meaning for "World Model", between Waymo/Deepmind's which is something that can create a consistent world (for use to train Waymo's Driver), vs Yann LeCun/Advanced Machine Intelligence (AMI) which is something that can understand a world.

I don't think there's a conflict. If you can predict the world you understand it.

1. Still hard not to think that this is a huge waste of time as opposed to something that's a little more like a public transport train-ish thing, i.e. integrate with established infrastructure.

2. No seriously, is the filipino driver thing confirmed? It really feels like they're trying to bury that.

I am very pro public transit. But there is still a place for cars (ideally mostly taxis). Going to more rural areas or when you need to carry more stuff. I think an ideal society would have both urban transit, inter-city transit and taxis for the other trips and going out into the country.

"The Filipino driver thing" is simply that there's a manual override ability when this profoundly complex and marvelously novel technology gets trapped in edge cases.

Once it gets unstuck, it runs autonomously.

As someone who half-learned to drive in Manila, the idea that they would use Filipino drivers as backups is ironic.

For context, my "driver's test" was going to the back of the office, and driving some old car backwards and forwards a few meters.

My view on Waymo and autonomous taxis in general is they will eventually make public transit obsolete. Once there is a robotaxi available to pick up and drop off every passenger directly from a to b, the whole system could be made to be super efficient. It will take time to get there though.

But eventually I think we will get there. Human drivers will be banned, the roads will be exclusively used by autonomous vehicles that are very efficient drivers (we could totally remove stoplights, for example. Only pedestrian crossing signs would be needed. Robo-vehicles could plug into a city-wide network that optimizes the routing of every vehicle.) At that point, public transit becomes subsidized robotaxi rides. Why take a subway when a car can take you door to door with an optimized route?

So in terms of why it isn’t a waste of time, it’s a step along the path towards this vision. We can’t flip a switch and make this tech exist, it will happen in gradual steps.

Automated taxis would still be stuck in traffic. Automation gets couple times in capacity, but the induced demand and extra cars looking for rides and parking will mean traffic.

Automation makes public transit better. There will be automated minibuses that are more flexible and frequent than today's buses. Automation also means that buses get a virtual bus lane. Taxis solve the last mile problem, by taking taxi to the station, riding train with thousands of people, and then taking more transit.

Also, we might discover the advantage of human powered transit. Ebikes are more efficient than cars and give health benefits. They will be much safer than automated cars. Could use the extra capacity for bike and bus lanes.

> There will be automated minibuses that are more flexible and frequent than today's buses.

In my sleepy metro area that has at least mid-tier respectable public transit (by US standards only), otherwise known as Portland, I think a lot of the routes would be better served by minibuses than full size. I wonder how the economics work out on that. Maybe dominated by labor? Tri-met drivers have a reputation of being paid handsomely as they gain seniority.

If everyone in NYC tried to commute in a single-occupancy vehicle, there would be gridlock -- AVs or no.

> Human drivers will be banned, the roads will be exclusively used by autonomous vehicles

I basically agree with your premise that public transit as it exists today will be rendered obsolete, but I think this point here is where your prediction hits a wall. I would be stunned if we agreed to eliminate human drivers from the road in my lifetime, or the lifetime of anyone alive today. Waymo is amazing, but still just at the beginning of the long tail.

It basically happened for horses.

rootusrootus 41 minutes ago|||
Did it? I did a cursory search and it seems like many places still permit horse-drawn carriages, just not on limited access highways. Sometimes with fairly onerous licensing and operational requirements (speed limits, poo management, etc), but still allowed.
xnx 11 minutes ago||
I think that will be how human-driven cars are in 30(?) years. Rare, but allowed with restrictions.

Drivers, however, absolutely do. And I do not see enough drivers voting away their own ability to drive any time soon.

A few years ago I would have (and did) considered the notion that manually programming was about to turn into a quaint relic and computers would be writing 90%+ of code preposterous. Once an alternative becomes obviously superior things can change very fast.

Right, I was pointing out that at some point there was probably a horse-rider constituency as there is a driver constituency today.

Is that:

- I would be stunned if we agree to eliminate human drivers from 100% of roads in the lifetime of anyone alive today.

or

- I would be stunned if we agree to eliminate human drivers from 10% of roads...

...or is there some other percentage to qualify this? I guess I wouldn't expect there to be a decree that makes it happen all at once for a country. Especially a large country like the U.S.. More like, some really dense city will decide to make a tiny core autonomous vehicles only, and then some other cities also do years later. And then maybe it expands to something larger than just the core after 5 or 10 years. And so on...

rootusrootus 37 minutes ago||
That is a fair point, since it is fairly safe to make "this absolute claim will never happen." And the person I replied to did say 'exclusively', which implies 100% elimination of human drivers. But still, I appreciate your nuance.

And in the spirit of that nuance, I will revise my statement slightly. I think it is entirely possible we will eliminate drivers on 10% of roads. We have rules that are analogous to that already with limited access highways. Though I would rate this still as unlikely, since such roads only make up just over 1% of all the roads in the US as it is. Not sure what the % is for other countries, probably less.

> some really dense city will decide to make a tiny core autonomous vehicles only

Agree 100%, this kind of thing I do expect to see happen. We already have exclusions for cars altogether in favor of pedestrians, so the precedent is set.

(2) I really don't understand why people are surprised that Waymo has fallbacks? The fact that they had a team ready to take over as necessary was well known. I've seen a bunch of comments about this and it seems like people are confused.

I think they're surprised to learn it's being done by a bunch of people on the other side of the world because they don't want to pay American wages.

I think you sort of fundamentally misunderstand the whole "steak vs sizzle" thing in capitalism?

The technology "feels" way less cool knowing that there are human backups, which would absolutely in turn make its percieved value go down.

They are not trying to "bury" remote assistance at all. They wrote a white paper about it in 2020 and a blog post about it in 2024.

Anyway you can think it's a waste but they're wasting their money, not yours. If you want a train in your town, go get one. Waymo has only spent, cumulatively, about 4 months of the budgets of American transit agencies. If you had all that money it wouldn't amount to anything.

"At all?"

Oh come on -- of course they are. That's precisely why you put it in a "white paper" and not, you know, ads.

Finally I understand the use case for Genie 3. All the talk about "you can make any videogame or movie" seems to have been pure distraction from real uses like this: limited, time-boxed simulated footage.
ActorNightly 5 hours ago||
This is cool, but they are still not going about it the right way.

Its much easier to build everything into the compressed latent space of physical objects and how they move, and operate from there.

Everyone jumped on the end-2-end bandwagon, which then locks you into the input to your driving model being vision, which means that you have to have things like genie to generate vision data, which is wasteful.

I wonder if they can simulate the Beatles crossing the street at Abbey Road in the late '60s
seanhunter 6 hours ago|
As a Londoner who used to have to ride up Abbey Road at least once per week there are people on that crossing pretty much all day every day reproducing that picture. So now Waymo are in Beta in London[1] they have only to drive up there and they'll get plenty of footage they could use for taht.

[1] I've seen a couple of them but they're not available to hire yet and are still very rare.

It doesn't look like they're going to open sources or anything, but I could imagine this would be great for city planning.

Or the most realistic game of SimCity you could imagine.

Very impressive work from Waymo. The driving with a tornado in the horizon example kind of struck my imagination, many people actually panic in such scenarios. I wonder though the compute requirements to run these simulations and producing so many data points.

Have been seeing Waymo test vehicles regularly around central London recently, operating at speed.

For shits and giggles, I did stop randomly while crossing the road and acted like a jerk.

The Waymo did, in fact, stop.

Kudos, Waymo
