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.

I'm doing nothing other than questioning where the induced demand is coming from. What is inducing if not increased efficiency?

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?

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 are describing how humans drive, not AVs. AVs always obey the speed limit and traffic calming signs.

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.

We haven't agreed on anything,I said I was open to your reasoning as to why those effects wouldn't happen, then you didn't provide any.

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.

You think you can eliminate all accidents through road design?

You are literally ignoring every single accident caused by distracted driving, impatient driving, impaired driving, tired driving etc.

Yeah, road design in America should be better, AVs should still also replace crappy wreckless humans. Those two ideas are not mutually exclusive.
