The whole point of induced demand in highways is that when you add capacity in the form of lanes it induces demand. So if our highways are already full and if that capacity isn’t coming from increased EV efficiency then where is it coming from? If there’s no increase in road capacity then what is inducing demand?
just for example: “freeing up both parking lot real estate, but more importantly, freeing up on street parking, creating more room for actual traffic to move”–every single one of these posited improvements would induce demand unless you literally demolish the infrastructure (which, if you’re just switching people one-to-one from regular cars to automated cars is not going to happen, because the number of cars will remain a constant). the existence of unused parking begets driving and is a predictor for more driving.[1] the existence of more space to move obviously begets more driving because the “highways” aren’t “full” anymore; and again, if it didn’t that would actually be worse because it incentivizes less safe driving practices.
You are describing how humans drive, not AVs. AVs always obey the speed limit and traffic calming signs.
if by AVs you mean “fully autonomous” ones that literally do not exist currently then sure–they better! but at that point nothing you say is meaningful, because the technology literally doesn’t exist. we might as well be talking about mass-adopted hydrogen cars or whatever.
but, if we mean semi-autonomous ones—the ones that clearly exist, and which companies advertise as autonomous, and which people actually use—no. absolutely not. these things routinely violate even the most obvious traffic laws and necessitate humans to intervene in their ordinary function. Waymo hits pedestrians even now, and it’s ostensibly one of the most advanced semi-autonomous programs in the world. Uber literally killed a pedestrian and got into legal trouble over it. Tesla’s problems are omnipresent to the point where the NHTSA has said their feature is unsafe in practice and people make it a punchline. you can’t no-true-Scotsman this technology. even in the best and least ambiguous traffic circumstances it has obvious problems!
↩︎In 2015, a group of researchers led by Chris McCahill looked at historical trends in parking supply and commuter behavior for nine cities: Albany, New York; Berkeley, California; the Washington, DC, suburbs of Arlington, Virginia, and Silver Spring, Maryland; Cambridge, Lowell, and Somerville, Massachusetts; and Hartford and New Haven, Connecticut. Using historical aerial photography from three dates to identify and approximate the parking supply, McCahill found that parking growth between 1960 and 1980 was a “powerful predictor” of car use in the following two decades. Every ten spaces added per one hundred residents before 1980 were linked to an 8 percent increase in the share of residents driving to work after 1980. Increase in the parking supply in the study’s first two decades was directly correlated with increases in car use in the following two decades. More parking appeared to cause more driving, not the other way around.
Yes, I have no doubt there would be induced demand, but that extra demand wouldn’t be at the cost of anything.
But if AVs add more capacity to our roads, that will be entirely because they are driving more efficiently.
you are literally doing what i mean when i say you are making assumptions with no evidence. there is, again, no reason to believe that “driving more efficiently” will result from mass-adoption of automated vehicles–and even granting they do, your assumption that this wouldn’t be gobbled up by induced demand is intuitively disprovable. even the argumentation here parallels other cases where induced demand happens! “build[ing] new roads or widen[ing] existing ones” is a measure that is almost always justified by an underlying belief that we need to improve efficiency and productivity in existing traffic flows,[1] and obviously traffic flow does not improve in such cases.
but granting that you’re correct on all of that somehow: more efficiency (and less congestion) would be worse than inducing demand. “efficiency” in the case of traffic means more traffic flow at faster speeds, which is less safe for everyone—not more.[2] in general: people drive faster, more recklessly, and less attentively when you give them more space to work with (especially on open roadways with no calming measures like freeways, which are the sorts of roads autonomous vehicles seem to do best on). there is no reason to believe they would do this better in an autonomous vehicle, which if anything incentivizes many of those behaviors by giving people a false sense of security (in part because of advertising and overhyping to that end!).
You’re asking for something that does not exist. How am I supposed to provide you evidence proving what the results of mass adoption of AVs will be when there has never been a mass adoption of AVs.
you asserted these as “other secondary effects to AVs”–i’m not sure why you would do that and then be surprised when people challenge your assertion. but i’m glad we agree: these don’t exist, and they’re not benefits of mass adoption nor would they likely occur in a mass adoption scenario.
For instance, what is your reasoning for believing that AVs could never be fundamentally safer than human drivers who are frequently tired, angry, distracted, impaired, impatient, etc?
the vast majority of road safety is a product of engineering and not a product of human driving ability, what car you drive or its capabilities, or other variables of that nature. almost all of the problems with, for example, American roadways are design problems that incentivize unsafe behaviors in the first place (and as a result inform everything from the ubiquity of speeding to downstream consumer preferences in cars). to put it bluntly: you cannot and will not fix road safety through automated vehicles, doubly so with your specific touted advantages in this conversation. the road designs that create bad driving behavior don’t cease to be an issue because people switch to an automated vehicle.
take for instance “Tackling Traffic Congestion,” Transportation Quarterly 40, no. 2 (1986), which states “growing congestion [in the Bay Area] […] is the result of development that comes with an improving economy compounded by a lagging expansion of freeway and transit capacity.” ↩︎
see for instance Leonard Evans, “Future Predictions and Traffic Safety Research,” Transportation Quarterly 47, no. 1 (1993): “although congestion impedes mobility, it increases safety, as measured by serious injuries and fatalities.” and Arnold Vey, “Relationship between Daily Traffic and Accident Rates,” American City 52, no. 9 (1937), who observed that beyond a certain point congestion reduced accident rates. congestion unsurprisingly acts as a calming measure when it becomes severe enough. ↩︎
As long as cars exist, AVs will be better than human drivers,
this is at obvious odds with the current state of self-driving technology itself–which is (as i noted in the other comment) subject to routine overhyping and also has rather minimal oversight and regulation generally. Tesla is only the most egregious example in both respects; even stuff like Waymo is pretty much entirely reliant on taking their word for it that the technology would be safer than humans (which meshes awkwardly with well publicized problems and efforts to hide robotaxi safety records).
Secondly, it’s based on the idea that people even can drive more than they already do.
they can. induced demand is omnipresent in basically all vehicular infrastructure and vehicular improvements and there’s no reason to think this would differ with autonomous vehicles
Fourthly, it ignores other secondary effects to AVs, like suddenly not needing nearly as much parking, freeing up both parking lot real estate, but more importantly, freeing up on street parking, creating more room for actual traffic to move, and their increased patience not causing constant traffic jams because they tailgated someone and then slammed on the brakes.
okay but: literally none of this follows from mass-adoption of autonomous vehicles. this is a logical leap you are making with no supporting evidence—there is, and i cannot stress this enough, no evidence that if mass-adoption occurs any of this will follow—and in general the technology is subject to far more fabulism and exaggeration (like this!) than legitimate technological advancement or improvement of society.
you’re being way too vitriolic here, dial it back by 10.
It’s not racist when they call him white boy, it’s racist he tells that story.
if you think calling people “white boy” is racist but the way he talks about indigenous people here isn’t you are such a fragile little cracker it’s not even funny
When South Korea started tackling this problem 20 years ago, it threw away 98 percent of its food waste. Today, 98 percent of food waste is turned into feed, compost or energy, according to the South Korean Ministry of Environment. It achieved this by banning food scraps from landfills and mandating that all residents separate their food waste from their trash and recycling — and to pay for the service through fees and fines.
South Korea is one of the few countries with a nationwide system for food-waste management. While France made composting food mandatory this year — and some cities like New York have imposed similar rules — few places match up with South Korea.
Colorado officials are now proposing to go further. In 2023, the state adopted legislation to try something that’s never been done in this country: automatically register tribal members to vote in U.S. elections.
The program, if implemented, would enable tribes to share their membership lists with Colorado elections officials, who’d then use that information to register every eligible person to vote, while giving them a chance to opt out. Since Colorado already mails ballots to every registered voter, this would necessarily mean getting ballots into the hands of more Native people. “We’ve made real steps forward, and we’re going to continue,” Colorado Secretary of State Jena Griswold told me recently. “We always try to push the envelope.”
And yet, Cloud is also keenly concerned that the program could make her community more vulnerable. For U.S. election officials to automatically register tribal members to vote, the tribes would need to share certain vital information about their members, such as full name, address, and date of birth. Cloud is hesitant to hand this data over to a state that has, over a long history that she knows too well, been an agent of violence.
there are definitely better, more substantive articles that can make all of the points this one is; accordingly, this will be removed. you’re free to find another article which makes this point though since it’s likely a conversation people want to have on here
One might find disappointing the disjunction between UATX’s tantalizing marketing and its conceptual yields. UATX had tweeted, “Dare to think with us,” had promised that they were “Not your typical summer school…,” had titled their program “Forbidden Courses.” But what was aired in this particular Forbidden Course were opinions neither audacious nor surprising. They were platitudes about the nature of man and woman, of the kind encountered in bad romantic comedies produced in the aughts. “Women are more complicated than men.” “There are things that women want that they don’t like that they want.” “With boys, their bodies and their desires are one.”
it’s… incredible how not-transgressive and not-marginal these opinions are
The European Court of Human Rights (ECHR) has ruled that weakening end-to-end encryption disproportionately risks undermining human rights. The international court’s decision could potentially disrupt the European Commission’s proposed plans to require email and messaging service providers to create backdoors that would allow law enforcement to easily decrypt users’ messages.

i’m not aware of any, it seems fairly straightforward and black/white in premise:
The prices will apply to vehicles weighing more than 1.6 tonnes with a combustion engine or hybrid vehicles, and more than 2 tonnes for electric vehicles. The move will not apply to Paris residents’ parking. [which i’m assuming here is equivalent to private parking on a home’s lot]
It’s been a shitfest for a while - it seems tailor-made for blowhards to speak authoritatively without having any real authority on an issue.
i’m sure plenty of people have made this joke before, but AI answers should have no problem fitting in with a culture of this sort!
i think it’s been gliding on the entropy of its original value for a long time at this point (it was founded in 2009)—certainly i can’t remember a time where it was useful, but then i only first encountered it in like 2016.
an amusing piece of trivia is that the correlation between this vote and the historical strength/weakness of the Paris Commune is quite high. much has changed in Paris since 1871, but the political geography largely has not:
removing this because it’s indistinguishable from spam; we’re not opposed to self-promotion here but it’s simply not a good first impression to post what is essentially an advertisement
Google “Search Liaison” Danny Sullivan confirmed the feature removal in an X post, saying the feature “was meant for helping people access pages when way back, you often couldn’t depend on a page loading. These days, things have greatly improved. So, it was decided to retire it.”
okay but… has it? this seems like an unfounded premise, intuitively speaking
One thing though: Criticism of admins should never be considered a rule breaking event provided it is not derogative or endangering, and if my reply to you is considered a reason for admin action then I need to reconsider my participation in beehaw as well.
just to be clear the issue here is/was not you critiquing me–i don’t care about that particularly, comes with the job–it’s the tone which seemed like it implied being held to any moderation standard was problematic. because they tend to cause a scene about how they’re being censored we’re not super interested in having people in that category on here, and so whenever someone responds in that way it’s a red flag
three paragraphs saying you’re wrong and that the empirical evidence supports nothing you’re saying is not a “long-winded rant” lmao–this uncritical “trust me bro it’s actually fine, you just don’t get it” stuff is the exact reason i consider autonomous vehicle stuff to 98% worthless techbro hype and autofellatio. cite your sources if you want people to listen–i have, and you’ve refuted none of it!
