When you make something easy to use, people want to do it more.

Enticing though they are, such arguments conceal a logical flaw. As a classic 19th-century theory known as a Jevons paradox explains, even if autonomous vehicles eventually work perfectly — an enormous “if” — they are likely to increase total emissions and crash deaths, simply because people will use them so much.

    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!

    1. 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.

      Look up Waymo, then stop going on long winded rants about things when you don’t even have a basic grasp of the current state of the technology.
