This community exists as a sister community/copycat community to the r/fuckcars subreddit.
This community exists for the following reasons:
- to raise awareness around the dangers, inefficiencies and injustice that can come from car dependence.
- to allow a place to discuss and promote more healthy transport methods and ways of living.
You can find the Matrix chat room for this community here.
Rules
-
Be nice to each other. Being aggressive or inflammatory towards other users will get you banned. Name calling or obvious trolling falls under that. Hate cars, hate the system, but not people. While some drivers definitely deserve some hate, most of them didn't choose car-centric life out of free will.
-
No bigotry or hate. Racism, transphobia, misogyny, ableism, homophobia, chauvinism, fat-shaming, body-shaming, stigmatization of people experiencing homeless or substance users, etc. are not tolerated. Don't use slurs. You can laugh at someone's fragile masculinity without associating it with their body. The correlation between car-culture and body weight is not an excuse for fat-shaming.
-
Stay on-topic. Submissions should be on-topic to the externalities of car culture in urban development and communities globally. Posting about alternatives to cars and car culture is fine. Don't post literal car fucking.
-
No traffic violence. Do not post depictions of traffic violence. NSFW or NSFL posts are not allowed. Gawking at crashes is not allowed. Be respectful to people who are a victim of traffic violence or otherwise traumatized by it. News articles about crashes and statistics about traffic violence are allowed. Glorifying traffic violence will get you banned.
-
No reposts. Before sharing, check if your post isn't a repost. Reposts that add something new are fine. Reposts that are sharing content from somewhere else are fine too.
-
No misinformation. Masks and vaccines save lives during a pandemic, climate change is real and anthropogenic - and denial of these and other established facts will get you banned. False or highly speculative titles will get your post deleted.
-
No harassment. Posts that (may) cause harassment, dogpiling or brigading, intentionally or not, will be removed. Please do not post screenshots containing uncensored usernames. Actual harassment, dogpiling or brigading is a bannable offence.
Please report posts and comments that violate our rules.

MODERATORS
I came here to point this out and love the way you stated it. Confusion, hesitation and unnecessary lane changes are what create traffic. There has never been a major highway development in history that didn’t cause at least some short term issues. We should give city planners a bit more credit than that
No, volume of cars is what creates traffic.
Edit: you'd think that in a fuck cars community, of all places, we'd all be able to agree on this basic principle. We're apparently infested with six idiot trolls who think cars don't cause traffic and that induced demand isn't real.
The volume of cars is a scale factor that determines the impact of traffic causing behaviors and conditions for free flowing highways (no traffic lights, stop signs, etc.). Following too closely and improper lane changing are two specific behaviors that actually create slow downs. There are numerous models that simulate this.
Yes, yes, I'm well aware of how it works (I'm a former traffic engineer IRL). Although it's true the behaviors trigger the slowdowns, it's the traffic volume that creates the conditions where switching to the congested flow regime becomes possible.
In other words, if high traffic volumes aren't present, those behaviors don't have that consequence, and moreover, if high traffic volumes are present, the free-flow regime is such an unstable equilibrium that some kind of event (even one as minor as a driver briefly tapping their brakes) triggering a shift away from it and to the congested regime is inevitable. It's the volume that's the essential condition, not the behavior.
