I don’t think this analogy is quite correct. Driving on a particular route is not a driver’s objective like reading a particular book is a reader’s objective. The driver’s objective is arriving at a destination. The objective in driving is not a finite resource, but the multiple route options to the objective can be, which differs substantially from a library queue.

Let's consider a library with both a manned librarian and a self checkout, two different queues, same objective. Let's call the self checkout the 'highway' queue and the manned one the 'surface street' queue. Each of which could be expanded to improve throughput (more lanes:more self checkout lanes, more streets:more librarians).

Ultimately the problem with anti-car rhetoric is that it seeks to limit access to the objective because it is "wrong" to use a self checkout lane and people must be forced to check books out in the morally correct manner.

No one (reasonable) has a problem with the library adopting a mobile checkout app, which let's call mass transit. But crippling self checkout to force adoption of the mobile checkout app could be at best described as a 'dark pattern', forcing people to check out books 'the right way' at the cost of overall readership.

I believe there is way too much value judgement placed here.

If you have two checkouts, people will use whichever one is faster (assuming everything else is equal). Make one faster, and people will shift from one line to the other. Though, to make it an even better analogy, make one line shorter, and people will start coming in from off the street rather than switching lines.

A much better example - telecommuting. IF commute is bad, one is strongly incentivized to have some work-from-home days. If the commute time is improved, then that incentive disappears and one would then consider commuting daily.

Induced demand I think is generally all about the idea that when something is painful - people don't do it. Take away that pain point, and people come. I don't begrudge people too much for driving, as an example I'll note I do my errands on a bicycle. As such, I'm strongly incentivized to make many stops and fewer trips. Meanwhile, I've noticed that people in my family will make a car trip errand as soon as the need comes up. "Oh, I need to go to the grocery store." They get back, then realize they also needed to go to the hardware store, drive out again real quick and back when had there been more planning, the two trips could have been combined. Switching to a bike is an extreme example to avoid the excessive/unnecessary trips that are made simply because it is so convenient. If the drive time were tripled, then there might be a behavior shift to group errands together. Why do so though if it takes just a few minutes to make the individual trips? Eventually the cost of the trip is sufficient that a person will start conserving, avoiding that cost (which can be: travelling in off-hours, grouping trips together, not doing a trip altogether, finding a different mode of transport, removing the trip by moving, etc...)

The people who freely use terms like "anti-car" always assume that the car is always the fastest most efficient way of getting anywhere... and then sit stuck in standstill on a 6-10-lane highway

[seadan83]

Ah, I think i just realized how to fix the analogy!

The issue is with how many books are checked out a time. If the line is absurdly long, at some point you will make fewer trips to the library to avoid paying the cost of waiting in line. You would check out more books so you would go less frequently. You would be trading storage space at home in exchange for time (not having to wait in line). If the line were infinitely fast, then why not go to the library exactly after you have finished one book to then go get one new book.

If an automated checkout then exists, the line time would be less, making it less expensive to go to the library, which means a person would be willing to increase their trip frequency to the library. Suddenly, you have a line full of people all checking out exactly one book, and returning the next day to do the same thing again (rather than checking out one weeks worth of books, and coming back a week later instead of the next day).

[lkurtz]

In your example, replacing bulky self-checkout machines (analogous to removing road/surface parking real estate) offers a significant benefit to everyone. More room for what everyone actually wants most: books. The preference for self-checkout machines forces a cost on everyone for the benefit of a few.

If you are stuck in gridlock in a two hour commute with a soulless car that functions as nothing more than an appliance, then sure, that sounds like my personal version of hell. But for me “The driver’s objective is arriving at a destination.” couldn’t be more of a false statement.

Give me a nice European sports car, a manual transmission, an empty highway and some nice scenery and commuting can be an incredibly relaxing experience. Even when I lived in the Bay Area commuting this way off-peak was awesome. In fact the commute was the highlight of my day.

> an empty highway

The best way to have an empty highway is to reduce the number of people who are driving because they have to do so.

[chgs]

How much are you willing to pay for all those resources and space you want to monopolise?

[BoingBoomTschak]

Same minus the highway (sports car != touring car). Well, Except that I have it: depressed man driving a new MX-5 in the south of France, driving is one of my last joys in life together with food and sleep.
