A look under our trunk: what's in our compute

Apologies for repeating myself, but it's hard to convey how far ahead Waymo is in every area: sensors, vehicles, training data, markets served, simulation, infrastructure, operations, regulatory.

They're growing fast, but I do wonder what they see as the bottlenecks: municipal approval, training, manufacturing? It's really unfortunate that lobbying is slowing self-driving rollout in some of the biggest and most important cities: NYC, Chicago, DC.

I just took a Waymo in San Jose, having taken a few from San Francisco - it dropped me off in a place that would have made sense in SF (across the street from my destination at a light, avoiding a U turn) but was terrible in the suburban streetscape where the road was literally 10 lanes 4 / 4 / 2 turning and no one would ever drop someone off like that instead of U turning so they didn't have to cross scary giant traffic.

So weird little things for scaling, but overall it was a good ride till that point. Also, the dropoff was at a hospital/clinic and Lyft for the return trip had no issue with going into the property to the actual destination.

Is it unfortunate, or just a different priority in a different place?

Those are also cities with a great public option for transit (unlike, say, Dallas or the Bay Area where different municipalities squabble). One might laud New York driving people away from car culture when the subways/buses can serve more people, greener.

Perhaps, but I can't think of why Waymo should be prohibited but not Uber or taxis.

Taxis and barely-legal app taxis both require a human to drive. Someone who's earning a living doing this, and paying taxes to NYC. Waymo is driven by a robot, owned by a company out in California, who has a lot of lawyers doing their best to avoid as much financial and legal liability as possible. Not that Uber and its ilk isn't doing the same thing but they've still got a tax-paying citizen in the loop.

The current mayor of NYC is a DemSoc so he might have some ideas about keeping NYC's money in the pockets of middle-class NYC citizens.

Buses and subways are not necessarily "greener".

30 people in 30 waymos vs 30 people in an electric bus?

No contest.

No contest when the bus is full, but the overall efficiency (/"greeness") of the system is much less clear considering: buses are rarely full, most buses are diesel, heavy buses tear up the pavement on their routes (especially near stops), and buses don't take riders directly to/from their destinations.

Different 30 people in the US. I’d drop my car if Waymo was around and financially made sense. You’ll never catch me wasting my time on a bus though. We’ll never even be close to Europe or elsewhere wrt where public transit was even decades ago in those places.

People here only ride the bus when there’s no other option for them.

Waymo could make a bus too anyway, especially after they’ve been in an area a while and have data about where they’d have the most impact. Internet at large would probably decry it as enshittification.

They really are the impressive tech, it's really a shame that they aren't the one capturing all the media spotlight.

I don't know if we'll get there eventually, but if we do, I won't be surprised if it's because of Waymo.

Riding in one is pretty mind-blowing at first. But what's more shocking is how fast you get used to it. After a while it's just a boring car ride.

I wish more people would experience it and see that the future is now.

It's beyond boring after a bit.

It reminds me of putting on noise-cancelling headphones in an already quiet room. You suddenly gain an appreciation for just how much quieter things could've been thanks to the contrast.

Similarly, having a vehicle accelerate/decelerate consistently, always taking turns with the same sharpness, etc.. all of it builds to this subtle feeling of the car ride fading into the background of the experience. You didn't realize those were features of a drive you could appreciate until experienced.

Very cool. To be honest, I'd assumed they were using commodity hardware, but no real reason for that. Cool chip. It is quite interesting that so many large companies have their own chips for these things. I almost managed to get my hands on a couple of accidentally liquidated MTIA chips but I was too slow. I wonder what the chip is like and what the dev experience is writing for it.

It would just be cool to see what these guys have cooked up dev tools wise since Google has always been famed for good developer experience (often to such a degree that Xooglers are useless outside the exosuit).

REing Meta's custom AI HW to get it running with something would be one hell of a project, and one hell of a flex.

It would rely on them being nice enough to leave at least some binaries on the thing though. Because I'm not sure how would one even get an in on how to boot the things without.

Downside of the MTIA chips is no open backend - so quite a lift to get them working if possible at all :(

It really doesn't say much. Tesla had more detailed talks on their HW and AI stack. This reads like a glorified marketing blurb.

I thought that was stalled because the mayor didn't like it?[0] Any new developments?

> New York abandoned its proposal to allow self-driving taxis earlier this year. New York City’s new mayor, Zohran Mamdani, has said he would heavily weigh the interests of taxi drivers in deciding on rules for the technology.
