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.

Tire rubber accounts for about 25-30% of all microplastic emmission on land. But we are talking about Q-tips and putting filters into washing machines, because the car lobby successfully stirred the discourse away from themselves.
@tryptaminev @mondoman712 How very true, not to mention the particulate air pollution which comes from vehicle tyres
@tryptaminev and that no matter what motor they carry 😬 #microplastic #tires https://phys.org/news/2022-11-unraveling-secrets-microplastics.html @mondoman712
It's probably even worse with EV-s since they're heavier than ICE cars of similar class/size.
@Shurimal urgh yes that definitely sounds worse :/ @mondoman712 @tryptaminev
@tryptaminev if we all switch to e-bikes, does this mitigate/remove the problem?
Pretty much. The tire abrasion is dependant on the weight and the speed of the vehicle. So unless your e-bike weighs multiple tons and reaches speeds of >100km/h, it will be much better than a car.
@squaresinger thanks. That’s what I figured. Maybe we can go back to cars with 1920s weight, speed and tire size
Kinda, yeah, that would help. A Ford Model T had 540-750kg weight, and a top speed of 67km/h. That's significantly lower than modern cars.
But a Ford Model A from 1928 already had 954-1144kg and was able to reach 104km/h, which is not too far off from the regular operating values of a small modern car.
If you'd use modern materials and engines, it wouldn't be hard to make a 500kg empty mass car with a top speed of 50-70km/h that fits 5 people, uses hardly any energy to move it and has very little tire abrasion.
If there were no heavy and dangerous cars around that you need to be protected from, something like an electric autorickshaw would be a perfectly adequate city vehicle.
@tryptaminev @mondoman712 the filter on the washing machine is my favourite. where am I supposed to clean it?
