I'd much rather all of the resources that are going into autonomous cars was instead going into proper public transit infrastructure. Cars are so hopelessly space and energy inefficient, and I hate driving them. If I could get around by bus, light rail, bike, and all of the wasted city space devoted to parking could be turned into more housing and amenities, that would be great.
I think it would be meaningful to also compare the fatality rates of the time tested and proven forms of public transit to these self driving cars too.
People always say this, but
a) even countries known for good transit like Japan still have a ton of cars for various things, and
b) there's no getting around that the money going into self-driving cars vs public transit isn't something that can really be swapped. It's coming from a different place for a different reason.
We absolutely could invest into more trains even with the SDC money flowing anyway, it's not like the SDC money is blocking it. We collectively choose not to do this, and it's not Waymo's fault.
A better idea would just be to let drivers pay the real price for the infrastructure they occupy and their negative externalities.
Then people would likely not have a issue with public transit.
"Let's make car owners more miserable" is a typical sentiment held by young, healthy people who live in dense cities and ride an electric bicycle to work.
Not everyone can do that. Many areas also completely lack the public transit infrastructure needed to support a normal life.
E.g., a couple of days ago, I was shocked to learn just how bad the UK public transport system really is, apparently, outside of major metros (https://news.ycombinator.com/item?id=49445286)

The negative externalities? On net the benefits are enormously positive, which is why every community around the world down to the very poorest, even illiterate societies (ancient civs were mostly illiterate and still built extensive road networks) will start clearing paths to make transport easier. It's an enormous social net benefit, the free, fast, efficient movement of people from one point of their choosing to another.

They also always hand wave the last mile problem. Last time this came up some folks were adamant that you could solve public transit and specifically last mile in a city like Dallas.
I welcome the car overlords like Waymo or related companies. I believe this is absolutely a step in the right direction and bringing up the public transit is sort of a “perfect is the enemy of good enough” situation.
Public transit doesn't really go that far, when you talk about the last mile it's pretty limited.
But I do like what you're going with that and maybe we could have public autonomous car infrastructure that we all share. And just one large global team working on awesome autonomous vehicles. That could be little pod type vehicles for one person and bigger ones as needed. Cuz the road system is pretty broad and amazing right now.
> the last mile it's pretty limited.
Where is that last mile exactly? In many metropolitan areas, you typically have available a broad selection of trains, subways, trams and/or buses of different sizes that takes you last mile. Some places even have special buses, like the "Neighbourhood Bus" we have here (https://www.barcelona.cat/mobilitat/sites/default/files/bcn-...) for narrow and steep neighborhoods up on mountains.
It's certainly doable, if you wanted to have last mile public transport.
Another consideration that needs to be made before tossing out private transit because "public transit is better" is not all people are able bodied, able, or willing to use public transit.
If it is 2am and you need to get home as a woman, it would be a no brainer to get in an autonomous vehicle while going on public transit is a bad coin flip on being harassed at minimum.
If you are wheelchair bound and the elevator is broken, wheelchair ramp is broken, or someone is already using the wheelchair spot, you just have to wait for luck to change.
If you have sensory difficulties that make public transit uncomfortable, private transit is always the better option.
The list goes on for many reasons and people that having only public transit would harm. The idea we can get rid of or otherwise push out private transit marginalizes everyone who isn't prototypical nor should we hand-wave that they can just rely on runs-on-other-people's-time disabled specific transports to get them into city centers because private transport isn't allowed in.

You said both "tram" and "neighbourhood" so I'm assuming you aren't in the US. I truly mean no offense, but it's hard to express how spread out even the most metropolitan areas are in the US.
Sure, NYC is one thing. But check out the ~10th largest city, Austin, where Waymo and other autonomous vehicles are (I think) in their largest deployment. Just on a map, or by density numbers, or whatever metric you want.
I'm in Austin, and Waymos rule. I walk most places, bike others, and rarely drive. I very, very rarely get a rideshare (and often get Waymo by way of Uber lottery). Autonomous vehicles exist, are real, and serve an actual need in this very low density city that most people on HN have heard of. I have 3 kids and if I could snap my fingers and swap them for Tesla Robotaxis (Waymos are better and safer!) I would in a second. I would even pay for that to happen.
If you're arguing about some idealistic society, that's one thing. In reality these things are way better than our public transit, and fixing public transit in a place this (not) dense is not as easy as you might think. The last mile is real, and people are coming from every direction and going every other direction and not willing to wait and transfers when these autonomous vehicles already solve the problems door to door so inexpensively.

Since many commenters do not understand that "the last mile" is a term of art and not simply 5,280 feet: https://en.wikipedia.org/wiki/Last_mile_(transportation)#Usa...
Trains and subways, by definition, are not serving you in that "last mile". The "last mile" is where you disembark from the closest rapid/public transport, but you still need to travel to your destination.
Every time you make someone switch modes of transportation to complete their commute, the suffering increases exponentially in my personal experience. I much prefer going door to door and getting the benefit of resting my mind and body.
I live in Switzerland. Public transit goes _everywhere_, even remote villages and mountains. This is by design, such that one can only use public transit to go almost everywhere in the country.
Is public transit always more convenient than the individual car ? No, but you can make the conscious choice of not owning a car, even if you need to raise a family. Switzerland has a high rate of car ownership, because we have a lot of money to spend. But many people, even if they own a car, will sometimes use public transit, because it is convenient, safe and comfortable.
There are places in Switzerland where if you need to take a taxi or an Uber, you will have to wait more than 30 minutes before one gets there. At this point, it is more convenient to take the regional bus that goes every 30 minutes. Even if the public transit frequency is every hour, I can plan my journey to arrive on the correct time (also, public transit is synchronised in the whole country to avoid waiting times).
I can see autonomous rideshares displacing taxi service and such. I think automonous rideshares still need density to be profitable. So if you need to subsidise rideshare to cover the whole country, why not properly invest in public transit?
Good for your country but also your country is quite small. I think a better analog is taking a trip from Zurich to Madrid. You could do it via train but it is probably going to be filled with lots of transfers and take 20 hours or you could take a 2 hour flight.

That's like a 15 minute walk. And with sufficient infrastructure investments this can be 5 minutes.
And when folks are given that option or driving they will always take driving.

This is where I've always assumed things were going. People talk about one day owning a self-driving car but I look forward to the promise of not owning a car, never needing to buy, maintain, register, insure, or drive one. Not having to buy into a depreciating compromise, do I prioritize economy or seating or cargo or...? Gas, hybrid, electric? Not having to hunt or pay for parking.
Private cars are costly and spend most of their time just taking up space.
We'll see if it ever works out that way but a boy can dream.
Sure just ping Tesla Connect. You dont even need to use the app or scan a QR code. It just reads your neuralink.
Rental scooters/bikes cover last mile service very well in my experience. I use transit a great deal more than I would if I had to walk so much on either end of the trip.
>Rental scooters/bikes cover last mile service very well in my experience.
Not so great for family trips, shopping around, etc.

I can walk a mile. Rarely have to in the city.
I think you need to re-read the parent comment, specifically this part:
> I'd much rather all of the resources that are going into autonomous cars was instead going into proper public transit infrastructure.
You're almost certainly an American, and you probably have no idea what public transit is like in countries that have been investing in it for decades instead of focusing 95% of their resources on infrastructure for cars.
Autonomous cars are pretty space and energy efficient if they act as public transportation. Cars spend something like 95% of their life parked. If AVs replace personal ownership, that's a HUGE reduction in the number of cars in existence. The future looks like a lot less parking lots and 8 lane suburban stroads.
So at 2am you would have thousands of cars driving around empty?
Or would you still need a giant spot of land to park these things outside of peak hour?
The giant spot of land could be in a much less convenient (= valuable) location if the car can take itself to and from there.

Roads designed for buses (and trucks) also cost many orders of magnitude more than ones build for cars only.
If you account for that, cost per passenger mile on fully loaded electric bus is more than uber chauffeur.
The problem with transit systems is that they aren't designed for competition. They're costly to make, have few builder companies to choose from (who all know the game very well and go over budget as a tactic), and extremely difficult to overhaul/retrofit when more efficient tech becomes available.
They're great for short distance travel in densely populated areas, but outside of that I doubt they'd hold up in long-term cost and efficiency vs autonomous electric cars for long.
As for parking, a fully autonomous car service would allow a car to come to you and pick you up. So it wouldn't need to park near where you are.
It does. About the same amount of money was spent in funding for Waymo as funding SFMTA over the period Waymo has existed. So in SF we are putting in as much money on public transit as Alphabet et al. is on Waymo and we both have the results we have.
>If I could get around by bus, light rail, bike, and all of the wasted city space devoted to parking could be turned into more housing and amenities, that would be great.
I guess it depends on where we're talking about. The majority of the US is not inside a city. So just diverting all resources into public transportation is only serving the metros.
If we're talking about a small country then sure.
> The majority of the US is not inside a city.
I think this isn't true for the US any more, maybe it hasn't been true for decades?
WorldBank seems to have the ubranisation rate at around 80% for the US: https://data.worldbank.org/indicator/SP.URB.TOTL.IN.ZS?locat...
There is a bit of a definitional problem, with people living in suburbs identifying as rural, as do folks in exurbs. I don't think they're considered rural, and they're concentrated enough that well-designed public transit could serve them quite well. A decent public transit system means that families in sub/exurbs can go from 2 cars to 1 car without a major drop in quality of life, but they'd save $5k - $10k per year.
It's much simpler than that.
UN urbanization rate is based on the national definition.
The U.S. definition of urban area is based on population (and has been changed recently):

We can have both. The resources aren't coming from the same bucket. Public transportation must be built by the local government, and is subject to that local government's ability to execute. In contrast, Self driving cars are largely siphoning resources from for-profit companies.
I live in the west side of San Francisco, and we may get a subway station by 2050 if we're exceptionally lucky. I'd rather have self-driving cars this decade, please.
> Public transportation must be built by the local government,
Amtrak is public transportation. Airlines are pretty close to public transportation. Local government doesn't need to be involved.
To my knowledge there are only a handful of public transit systems in the world that operate at a profit, let alone that operate at enough of a profit to recover construction costs. As in, maybe 5 if you squint really hard. Who do you expect to fund new ones if not the government?

Small self-driving busses would do exactly what you want. The cost of increasing bus service is overwhelmingly the cost of bus drivers. If the busses could drive themselves, cities could afford to deploy a lot more busses, especially smaller busses, running much more often.
As for light rail, in the US, light rail projects can typically cost hundreds of millions of dollars per mile. The NYC 2nd Avenue subway expansion cost billions of dollars per mile.
And, if you want people to stop wasting city space on parking, self-driving taxis are exactly the right solution.
If buses are autonomous, it no longer makes sense to have arbitrary routes that people need to wait at a bus stop for. They can wait in parking lots, charging their batteries, until they are summoned, and give people door-to-door transportation.
It sounds like an autonomous taxi, but not necessarily. A taxi usually has only one rider, whereas a bus would have more seats, and potentially pick up and drop off other riders that are more-or-less on the way. This is Via's Microtransit[1] model, but without the cost of a human driver, it becomes much more cost-effective to deploy at large scale.
[1]: https://ridewithvia.com/solutions/microtransit
That model doesn't really work with high demand I wouldn't think. The thing with the fixed route case is you no longer have to serve the many edge cases, you force people to solve it themselves and maximize the service you can offer over a more collectively beneficial routing.
> And, if you want people to stop wasting city space on parking, self-driving taxis are exactly the right solution.
Self driving taxis have to be parked (or cruise around continuously), I guess, and that parking better be close cause ain't no one waiting for a self driving car parked 30 minutes away to get moving.
>all of the resources that are going into autonomous cars was instead going into proper public transit infrastructure.
They need not be separated. This is the entire point of the Cybercab and the Cybervan: Get self-driving cars, vans, etc. with the one job of moving people around. They only park to recharge or repair.
Demand is based on time of day/week/month/year.
Where do all those cars needed during peak demand go? They're going to be parked somewhere and it's not going to be in the middle of nowhere, because that's an awful customer experience.
The same place as existing taxis and busses? Busses are a worse customer experience than a 10 minute wait.
> I'd much rather all of the resources that are going into autonomous cars was instead going into proper public transit infrastructure.
Solving the last mile problem also helps solve the public transit problem.
The issue in the US is that the current population configuration does not have single population points connecting to single employment points like back in the days of the mills or the factories. As such, public transit becomes difficult.
For example, the train in Southern California is hampered by the fact that you need huge parking lots and cars at the transit stops. If you can take an autonomous vehicle at either end, that evaporates and a LOT more people can now make use of the train effectively.
AVs and public transportation are not comparable. The cumulative lifetime investment in Waymo would not fund even half a year of capital expenses for the New York MTA, for example.
I'm not sure that's a fair comparison. The most expensive part of self driving cars is building the roads and highways. Would make more sense to compare Waymo to the operating expenses of PT, hiring the drivers and maintaining the trains.
Building roads for buses are _few orders of magnitude more_ expensive than roads for cars only.
Unfortunately we still have trucking, but it's starting to feel we should build separate roads for them and for special cases only allow multi-axle delivery trucks on normal roads.

You are suggesting that we should attribute a fraction of the costs of our road building and/or maintenance under autonomous vehicle development? If so, what fraction are you proposing?
