In the US, 11 deaths per billion miles driven (or about 47k per year) is currently seen as an OK cost.

More than twice as much per mile as places like Sweden and Switzerland, and still substantially more than places like Canada, Australia or Germany (all three in the 6-8 deaths per billion miles range). So it's not like there isn't room to improve. The effort to do so just isn't seen as worth the cost at the societal or government level

Turning that into a monetary cost would change the ethics slightly, but it wouldn't be a monumental shift

The issue here is that a lot of the concerns about AV's are orthogonal to the standard metrics of concern.

I'm a strong transit alternatives advocate, but even I recognize that a firetruck or ambulance being blocked by an AV has the potential to cause an outsized amount of death and destruction, because deaths aren't always linear and a fire that is able to get out of control can do catastrophic damage compared to a single out of control vehicle.

I'm genuinely stunned that AV's do not have the ability to be "commandeered" by Police/Fire/EMS in a pinch, and I'm honestly surprised that regular citizens can't just hit a red button that signal "this is seriously an emergency." These are fairly simple steps to mitigate the tail risk of AV's but the platforms aren't going to prioritize that if there are no incentives.

  • We already accept that it’s fine for human drivers to block emergency services and we generally refuse to build, say, bus and bike lines that can be used by emergency services.

    So the uproar over AV’s blocking emergency vehicles seems incredibly manufactured or inconsistent, much like the hoopla over AI and water.

    e.g. You can take anyone complaining about this and you’ll find they didn’t care about emergency vehicles or water until just now regarding one thing. I’d like to see some consistency.

    • The difference is blocking emergency vehicles in predictable, high traffic areas that can be intentionally avoided vs randomly blocking an entire road because you couldn’t handle a weird event.

      People actually think hard about these problems. The entire point of my post is that it is trivial to mitigate.

      I was in the middle of the SF blackout, and witnessed the Waymos stopped at lights and actually commended Waymo for handling the emergency so well. At the same time, I’ve seen many ambulances get blocked just seconds away from the hospital because of Waymos unable to navigate complex intersections like oak/fell and stanyan.

  • > I'm genuinely stunned that AV's do not have the ability to be "commandeered" by Police/Fire/EMS in a pinch, and I'm honestly surprised that regular citizens can't just hit a red button that signal "this is seriously an emergency."

    The passenger of a Waymo can, but not anyone outside it. There's a very prominent "call for help" button on the screen when you get inside.

    • A “call for help” button is customer service. The ability to say “this is the police, drop everything and attend to this car” button would be helpful.

Don't forget to add rail incidents to that metric. I live in Spain, this year we had 4 derailments for a total of 48 deaths and 195 injured. The USA has had 0 passengers killed or injured from train accidents this year. Portugal had 15 death after a tram derailment. In Amsterdam, the tram is more dangerous than the car.

Also Germany is very high (for European standards) because of the Autobahn. They can save around 140 lives a year by having a limit on the Autobahn but the car lobby in Germany is very strong. Those 140 lives are seen as an OK cost just to go vroom on the Autobahn.

  • >I live in Spain, this year we had 4 derailments for a total of 48 deaths and 195 injured.

    Which, to be clear, is a considerable outlier. Highest since 2013 and about double the deaths and 4x the injured of a "normal" year.

    Not to mention that trains are far safer than automobiles too.

    >The USA has had 0 passengers killed or injured from train accidents this year.

    Is this a fantastic, magical year or something? The normal number seems to be around 800 a year? https://www.kochandbrim.com/study-train-accident-deaths/

    • > Not to mention that trains are far safer than automobiles too.

      This claim is situationally true, but not universally so like many people seem to believe. For example, Brightline rail service in Florida has been operating since 2017 and averages (by my math) 29.8 deaths / 100M passenger-miles, while the road system in Florida averages 0.89 deaths / 100M passenger-miles. Those deaths are mostly not suicides, and imo we should treat pedestrian deaths from trains as substantially more morally weighty than passenger deaths, since it's a victim that didn't opt-in to the risk.

      For what it's worth, the unusual spike in Spain train crashes this year seems to have pushed them barely over the fatality numbers of Spanish cars (0.91 deaths/100M pax-mi vs 0.73 for cars) but that's pretty clearly an outlier.

      If you measure per vehicle-mile rather than per passenger-mile I'm pretty sure trains are always way more dangerous, although that's a less fair comparison.

    • Your number includes suicides, trespassing and more. Only 24 passenger deaths in a ten year period.

  • Hm, it's only something like 10% of German traffic fatalities that occur on the autobahn. And according to wikipedia, Germany doesn't rank high in terms of traffic fatalities, even by European standards. France has a similar number of highway deaths. I'm personally not a fan of the autobahn and especially not the unrestricted speed. It seems obvious that it should cause lots of fatalities, but the evidence for it just doesn't seem to be there.

  • What. in god's name are you saying?

    > Don't forget to add rail incidents to that metric. I live in Spain, this year we had 4 derailments for a total of 48 deaths and 195 injured.

    Yeah and how many in the 15 years prior? 112. Of which 80 were in a single (TGV) crash.

    How many people die each year in Spanish roads? Thousands.

    > The USA has had 0 passengers killed or injured from train accidents this year.

    Can't have rail accidents if you don't have rail *taps side of head*

    > Portugal had 15 death after a tram derailment.

    Oh my god, after a 140-year old tourist attraction malfunctioned! Hardly representative of any transit system whatsoever.

    > In Amsterdam, the tram is more dangerous than the car.

    This is just not true, by any metric.

    And also, why are cars comparatively less dangerous in Amsterdam than in most other places? Because it is not designed for cars first, there are low speed limits enforced by traffic calming (like speed humps and narrow cobbled streets) everywhere.

    • > Can't have rail accidents if you don't have rail taps side of head

      The USA has the world's largest network with 220000 kilometers of rail

      > This is just not true, by any metric.

      In Amsterdam the tram is 57x more deathly than the car.

      https://www.parool.nl/nieuws/al-twee-doden-dit-jaar-hoe-onve...

      Trams in Amsterdam should be replaced with busses. Busses stop much faster and don't weigh as much. Trams are literal death machines. It's really scary to ride bicycle in Amsterdam and hear the ding-ding-ding when you are about to be run over by a tram and you quickly have to move over.

      Also you seem to be a bit confused, Amsterdam does not use narrow cobbled streets for traffic calming. Maybe you are thinking of France or Belgium.

    • > Can't have rail accidents if you don't have rail taps side of head

      Sure the US has low rail-usage per-capita, but it's still enough for 50% more passenger-kilometers per year than Spain.

Coming from a bio background, I’ve always been confused why auto fatality stats are normalized per miles driven. Epidemiological metrics like incidence or prevalence seem like they would work fine? Town A would be “safer” than town B if people’s commutes are 20% shorter, even if accidents occur w same frequency

  • Pretty sure I've seen exposure-adjusted incidence rates used in clinical trials.

    Miles is simply a proxy for exposure.

    Given risk here does vary by exposure time and trip length varies so much, it seems reasonable to use - at least in combination with crude rates.

    • Fair point - a combo might be the best approach.. I understand the idea of accidents correlating w/ miles driven, but it seems to be optimizing for driving safety rather than human life? Does that make sense?

  • Because it yields a simple corollary that to make travelling safer you can reduce the number of miles driven. Mostly by giving people viable alternatives to driving, be it long-distance rail or bike lanes to move around quicker and safer in the city.

> it's not like there isn't room to improve

Losing one's license means destitution for many Americans. That places practical limits on enforcement compared with less car-oriented countries.

  • I'm from Belgium, and even with public transportation, there are a large group of people dependent on their driver's license.

    But if you ask someone if they'd drive without insurance, or without driver's license they look at you like you've asked them to do the impossible.

    Whereas in the US no-one bats an eye when that happens. Half the time the cops just issue a ticket, and don't even tow the car.

    And now people who obey the law need to take out extra insurance for under/uninsured motorists.

    • > there are a large group of people dependent on their driver's license

      Are there "no licence cars" in Belgium and the US ? Basically a moped motor and a seat inside a box. 45kmh and no highway, but a bit more confortable and fast than a ebike for rural environment.

    • You are right that this happens frequently in the United States compared to Europe, but you are overstating the degree to which this culturally and legally acceptable. People who are doing this are not typically broadcasting it to others, and I can assure you that when they do, for the most part people will tend to "bat an eye" at the very least.

      Note that motor vehicle insurance in most of Europe is more tightly regulated and generally more affordable than in the United States. Also, I suspect the car-dependent individuals in urban areas with robust public transportation in Belgium are generally vastly higher income than the typical uninsured compulsory driver in the United States. Happy to be corrected though

      A lot of the people driving without insurance or licenses in the US are illegal immigrants, which means enforcement of driving illegally is caught up in the same cultural-war fight over immigration law enforcement that has dominated American news since Trump got re-elected. "And now people who obey the law need to take out extra insurance for under/uninsured motorists" is specifically an anti-illegal-immigrant talking point.

  • > Losing one's license means destitution for many Americans.

    That'd be the same for a Swede who lives in the middle of nowhere too. Although I'm sure both groups, if they'd loose their license, would continue driving anyways.

    • Clearly, a bit weird to assume that no license would automatically mean that the driver stops driving, that's not true at all.

    • ...But what percentage of Swedes is that? vs the vast majority of working-class Americans.

      Remember, outside of its few biggest and wealthiest cities, the US just does not have decent, reliable public transport, and most places don't have any.

  • Tons of options other than removing the ability to drive. More stringent enforcement, higher fines.

> So it's not like there isn't room to improve. The effort to do so just isn't seen as worth the cost at the societal or government level

That effort being what, exactly?

Road fatalities per mile driven don’t translate cleanly from country to country because the type of roads and even types of deaths (single vehicle, multi vehicle) are different.

We could set the speed limit at 25mph everywhere and force all vehicles to not exceed that limit and that would make the number go down, but the cost would be extreme for everyone.

So what, exactly, are the solutions you are proposing?

  • > That effort being what, exactly?

    Off the top of my head you could do any of these or a combination.

    - much stricter training and testing to get a license

    - vehicles where the safety of others is considered

    - ban stupid dangerous cars (my wife doesn’t stand as tall as an F350, let alone a kid

    - harsher penalties for drunk driving (see Germany)

    - harsher penalties for all kinds of dangerous driving

    None of these are hard to implement, the US just lacks the will.

> 11 deaths per billion miles driven

You should calculate how many are "single vehicle accidents" and how many are "multiple vehicle accidents." In the US the majority are single vehicle.

> seen as an OK cost.

You cannot build a system that stops every stupid person from doing something stupid without introducing absolute tyranny.

Doesn’t that 11 per billion statistic include commercial drivers as well? And doesn’t the United States have by far the largest percentage of commercial miles driven of any developed nation?

There’s a far cheaper solution available. Log books.
