This weekly roundup thread is intended for all culture war posts. 'Culture war' is vaguely defined, but it basically means controversial issues that fall along set tribal lines. Arguments over culture war issues generate a lot of heat and little light, and few deeply entrenched people ever change their minds. This thread is for voicing opinions and analyzing the state of the discussion while trying to optimize for light over heat.
Optimistically, we think that engaging with people you disagree with is worth your time, and so is being nice! Pessimistically, there are many dynamics that can lead discussions on Culture War topics to become unproductive. There's a human tendency to divide along tribal lines, praising your ingroup and vilifying your outgroup - and if you think you find it easy to criticize your ingroup, then it may be that your outgroup is not who you think it is. Extremists with opposing positions can feed off each other, highlighting each other's worst points to justify their own angry rhetoric, which becomes in turn a new example of bad behavior for the other side to highlight.
We would like to avoid these negative dynamics. Accordingly, we ask that you do not use this thread for waging the Culture War. Examples of waging the Culture War:
-
Shaming.
-
Attempting to 'build consensus' or enforce ideological conformity.
-
Making sweeping generalizations to vilify a group you dislike.
-
Recruiting for a cause.
-
Posting links that could be summarized as 'Boo outgroup!' Basically, if your content is 'Can you believe what Those People did this week?' then you should either refrain from posting, or do some very patient work to contextualize and/or steel-man the relevant viewpoint.
In general, you should argue to understand, not to win. This thread is not territory to be claimed by one group or another; indeed, the aim is to have many different viewpoints represented here. Thus, we also ask that you follow some guidelines:
-
Speak plainly. Avoid sarcasm and mockery. When disagreeing with someone, state your objections explicitly.
-
Be as precise and charitable as you can. Don't paraphrase unflatteringly.
-
Don't imply that someone said something they did not say, even if you think it follows from what they said.
-
Write like everyone is reading and you want them to be included in the discussion.
On an ad hoc basis, the mods will try to compile a list of the best posts/comments from the previous week, posted in Quality Contribution threads and archived at /r/TheThread. You may nominate a comment for this list by clicking on 'report' at the bottom of the post and typing 'Actually a quality contribution' as the report reason.

Notes -
I found this blog when I was trying to figure out what a “Soviet triangle” meant. Thought it was interesting reading. That article is about bus networks, but there are others on subway placement, throughout, all sorts of stuff.
Those certainly disincentivize traffic, but I’m not sure I grasp the economics. Taxing consumption reduces the clearing quantity. But the clearing quantity for roads is the supply of workers! Any intervention that doesn’t change the ratio of road usage per worker is going to affect the cost of labor, too.
So we need to ask whether self-driving cars fundamentally changes that ratio. I think it has to, right? Flawless zipper-merging. Reduced accident rates. Shorter following distances, perhaps ending in attached convoys to reduce drag. There’s a lot of room for technical solutions.
I don’t think we’ve hit the limit on people-miles per hour. Until we do, we still have room to make congestion more efficient.
I think you make a pretty important point: Many, if not most, drivers in cities don't even want to be there. They are there to get the paycheck to do the things they actually want to do. Thus any "solution" to too many people driving in the city will inevitably end up hollowing out that industrial/urban core of office buildings. We've seen this story before. This kills the city.

Pedestrian Observations is great! I don't know any better source for highlighting transit economics and (especially) instances of transit agency incompetence.
Taxing consumption should lower road usage per worker, because it makes workers more likely to bike, carpool, or take transit.
