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.

The use of tires will be a daunting thing to change. If somehow we all managed to change to bicycles for instance, there are still tires.
The wear is drastically different, at least.
Probably easier to develop an alternative too when it doesn't need to support two tons.
The amount of wear on the tires of a bicycle which let's just assume the heaviest person riding the heaviest e-bike would be a few hundred pounds wearing on the tires? Compared to several tons for an auto pressing down on 4 tires it's a LOT less.
If a solution reduces a problem by 99% I'd say that's a damn good solution. Instead here we are, clapping and rejoicing when the car companies say the new model is 5% more fuel efficient or 3% lighter over the ongoing model.
The trend of most new vehicle sales are larger and heavier :(
Yup and, as the article states, electric cars are even worse.
As per the quote below, a car loses about 0.08g of tread per km.
Compared to a car, a bike tyre is about the same diameter, 10% of the width (~20mm), 28% usable tread depth (~2mm), has 50% less wheels, and can travel 10% the distance (~10000km).
This suggests a (very approximate) tread loss of 0.08 * 10% * 28% * 50% / 10% = ~ 0.01g per km for bicycles.
For replacing longer car journeys less typically travelled by bicycle, rail transport is the best solution and removes the issue of tyre wear.
Quoting [deleted] in r/theydidthemath:
Your model fails to account for weight of the tyres, which has a big impact. I can't figure out what that ratio is though.
Yeah way to not think about the problem or its multifaceted solutions at all. Just write out the first thing that pops into your head and hit post.
