I think it makes sense to do an ASIC later, but not now. Chip development is expensive and risky. They ought to at least start selling a product with positive gross margin first.

Its possible that they have tried that and the market isn’t giving them what they need at the price they want. I do mostly agree with you though; its the economics of the car thats gonna supercharge adoption.

EDIT: another commenter mentioned that their platform is used by other companies (VW perhaps?). With that information, it might make more sense to do this.

> Autonomy has diminishing returns here; it doesn't magically prevent the chaos of mixed-use environments. It doesn't prevent chaos, but it does provide ubiquitous cameras. That will be used against people. I'm ambivalent about that and mostly in a negative direction. On the one hand, I'd very much love to see people who cause accidents have their insurance go through the roof. On the other hand, the insurance compan…

> I'd very much love to see people who cause accidents have their insurance go through the roof.

Life is hard and people make mistakes. Let the actuaries do their job, but causing an accident is not a moral failure, except in cases like drunk driving, where we have actual criminal liability already.

> the insurance companies will force self-driving on everybody through massive insurance rate increases for manual driving.

Why would manual driving be more expensive to insure in the future? The same risks exist today, at today's rates, but with the benefit that over time the other cars will get harder to hit, reducing the rate of accidents even for humans (kinda like herd immunity).

> Given that we do not have protections against companies that can make you a Digital Non-Person with a click of a mouse, I have significant problems with that.

I absolutely think this is going to be one of the greater social issues of the next generation.

I have a plex server and use Prologue for audio books. What would my experience on Rivian be like? I am guessing I would have to connect to the infotainment system as a bluetooth speaker? Would I be able to easily skip forward/backward and see the current chapter? I've been using car play for the better part of the past decade and don't know what it looks like in vehicles without it.

I think the revenue source times number of people using Plex for audiobooks as a total market value for Rivian is approximately zero.

What if you listen to audio books with a 3rd party app that you really like, but it's not on rivian?

I would expect you can still skip forward and back, and read titles. So as long as you start before you drive you might be gucci?

I hear this a lot and it's surprising to me. We have three cars in our family (two with carplay and the Rivian) and carplay always feels like such a downgraded experience compared to that of the Rivian.

I don't know about Rivian, but last time I used bluetooth in a car you could see current title, play/pause and skip forward and back.

But that is all, no playlists control.

> Or by a train to do the long miles and then other modes of transit once you're closer Of your many points in various posts, this is maybe the only point I'm really on board with. Amtrak already supports this, even. My car can drive me to the train and then the train can do the long haul, and at the other end my car will drive me off the train and to the destination.

This isn’t strictly directed at you, but I’m saddened that HN is immediately ready to dream big when it comes to solving hard problems and making the world a better place in spaces like AI, crypto, and technology in general. But suddenly shuts down over things as simple as trains, buses, and bike lanes.

There’s plenty of examples of guerrilla urbanism that I think align closely to the hacker ethos. Even more these problems are very solvable and can net huge gains in metrics without having to “dream for a century”.

> waaaaay more rail routes

It’s actually much simpler, Amtrak just needs right of way along with some other straight forward regulations to help balance freight and transit on America’s railroads.

Amtrak has also been doing great at incremental expansion and brining back (or increasing!) ridership just in the 5 years since the pandemic in a number of areas like Chicago to Milwaukee, and in the PNW.

The defeatist attitude isn’t what I expect from HN. You already found the best piece of actionable advice which is to look for incremental ways you can adjust your life to be different. My wife and I hardly drive anymore. Most of our trips: her work, groceries, restaurants, most leisure activities, etc are now by bike. We live in the suburbs too, a full 10 miles (20-30min drive and across an interstate) from the city’s downtown.

Cars are only perceived as necessary in America bc it is assumed that they are. There are many small and safe ways to shed the car dependence and they’ve all been huge positives to my life. We’re happier, healthier, building more community, spending less money on gas and maintenance. It’s nice.

I doubt autonomous car makers will offer this themselves. They'll either partner with existing insurers or try to build a separate insurance provider of their own which does this. My guess, if this actually plays out, is that existing insurers will create a special autonomy product that will modify rates to reflect differences in risk from standard driving, and autonomy subscriptions will offer those in a bundle.

Bundling a real product with a financial institution is a time tested strategy.

Airlines with their credit cards are basically banks that happen to fly planes. Starbucks' mobile app is a bank that happens to sell coffee. Auto companies have long had financing arms; if anything, providing insurance on top of a lease is the natural extension of that.

I'm really doubting this is the case. It seems much more likely to be due to zoning laws.

It's not really. If you have cheap, abundant land it makes no sense to build densely. Look at Houston with ~zero zoning laws and ~infinite sprawl. "A neighborhood" in a high-sprawl suburb wouldn't be able to support local mixed use amenities because even singular "neighborhoods" are gigantic enough to warrant driving across them. Once you're in the car, why would you go to the place 2min down the road instead of the…

Houston doesn't have zoning laws, but it does have private deed covenants enforced by the city which effectively work as zoning laws. https://www.houstontx.gov/planning/Neighborhood/deed_restr.h...

This is better solved by leveraging more traditional forms of transportation. Making biking, walking, and various forms of transit easier, safer, and more effective. Cars, whether self-driving or not, are in direct opposition to this. I'm sure they could be useful to folks that have the specific use-case for it, but the vast vast majority of trips in a person's day-to-day are better solved by robust multi-modal optio…

I agree with you broadly in principle, but sadly cities in North America have been built for cars, and so they are by far the best way to get around

I actually see this as a benefit! Cars take up a lot of space and so now there exists massive right of ways that can be used and modified for other transit modes. Take a lane away from personal cars and dedicate it to buses so they can run faster and avoid traffic. Remove some street parking spots and create a protected bike lane or a street market or something else. The extra space can be a huge boon. It’s pavement, basically a blank canvas imo.

Public transit is a dream turned nightmare consistently for seventy-five years. Autonomy will be less efficient -- but not that much less efficient given closer car spacing, speed, and remote parking -- but it will be spectacularly more convenient and comfortable. I'm all for it. You'll survive the tire pollution.

> You'll survive the tire pollution. I tend to expect better from HN commenters. I don't have an interest in having a discussion with such a callous and dismissive comment. I hope your day gets better. Tire pollution is worse than tailpipe emissions and the full effects aren't known. You're dismissive of other people's and the environment's health and you're wrong. https://www.theguardian.com/environment/2022/jun/03/…

A typical ICE car will consume at least 500 gallons of petrol (gasoline) per 1 gallon of tire tread worn. The environmental impact per volume of tire is certainly greater, but it's not remotely five hundred times greater.

I'm not saying we should disregard the issue of tire pollution. But if it was as serious as you suggest, it would be making more headlines than it is.

Most traditional OEMs in the automotive industry are integrators. They write a specification, and a Tier 1 supplier provides a black box matching that spec. (Tier 1 in turn provides a spec to its suppliers and integrates their parts) This has several consequences - Tier 1 suppliers are waiting on input/approval from OEM before proceeding with projects - Tier 1 suppliers don't necessarily have the capital to do work "…

Don't many automakers outsource level 2 driving aids these days? Typically someone like Mobileye?

Level 2 is simpler and more mature, so it should be easier to specify, package and integrate.

It can follow the traditional OEM outsourcing route, where OEM has high-level models and gets suppliers to implement the details. e.g. I can find public information that Subaru use Veoneer cameras, Xilinx chipsets, but defines their own algorithms. I would speculate they have an outsourced company convert algorithms to FPGA netlists/embedded code. (On the other hand, I know other OEMs have a more complex mesh of joint ventures)
