Fuck Cars
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.

I partially agree with you. They need a better explanation of what they were measuring for and how they came to their conclusions. Also PM2.5 may be too large to capture all the exhaust particles, a quick Google search shows some results saying 2.5 for combustion particles and others saying 2.5-1.0. PM2.5 is generally considered to be the most harmful to human health and they stay in the air longer than larger particles so maybe that's why they chose to only measure that?
But, just because the volume of gas a car uses far exceeded the volume of tire it uses does not mean that the burning of gas creates more pollutants. Theoretically, the only products of combustion are water and carbon dioxide. We know that we don't get perfect combustion, there are additives that affect things, the time in the combustion cylinder isn't ideal, and the air to gas ratios aren't always right. If we had perfect combustion water and CO2 may not be considered pollutants. Both occur naturally and have natural processes to be reused. Generally we do think of CO2 as a pollutant because we produce it in much great quantities than it naturally would be created. They exclude CO2 from their study, we know this because CO2 is much smaller than PM2.5.
It didn't really occur to me to consider an interpretation of "emissions" that excludes CO2. Had they stuck with the word "pollutant," then sure, but what they said was "emissions."
There's probably some reasonable interpretation of these findings that's productive and useful, but I think whoever wrote this is playing a bit fast and loose.
