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.

No. That only solves some of the issues, and creates brand new ones.
You haven't solved the inherent inefficiencies of having everyone sit in their own cars. The same bottlenecks will still exist and will still cause congestion, only with automation you can have slightly more capacity because it's taking out the delays between one driver moving and the driver behind reacting and starting to move as well.
All the issues with tires rubbing asphalt creating micro rubber particles will stay, as will the massively cost ineffective infrastructure needed to support mass car travel like freeway interchanges, as will the fact that you need orders of magnitude more materials to manufacture enough cars to do the job of just a few hundred trains.
And having the cars autonomous will make them even more vulnerable to cyber attacks than modern cars already are.
Also, trains are even easier to automate than cars. I live in Vancouver and we've had autonomous trains since 1986.
@HiddenLayer555 In NYC, my example, how many more train lines do you suppose you would need? Above ground? Underground? Are you going to lay track on every street? underground? Are you sure this would be more efficient than a network of smaller vehicles? There is no need for everyone to sit in their own car if it is all electric and automated. A single person vehicle, if if even existed, could be much smaller.
Unironically yes. Tear up all that fucking asphalt and replace with paving stone and/or grass, with tram tracks embedded. Streets would be so much nicer without all the hot black asphalt and dirty annoying loud cars.
@balsoft That would be a big improvement in the end, but filthy to accomplish.
As the Netherlands had showed us, you can do it incrementally just by repaving old streets when their time comes.
@farbel @HiddenLayer555 Not much more, PT already moves more people than private vehicles around NYC: https://a816-dohbesp.nyc.gov/IndicatorPublic/data-explorer/walking-driving-and-cycling/?id=2415#display=summary
So to get from where it is to a "no private vehicles" utopia thre isn't that much more to do. Probably as tramways on roads that will now be closed to cars. So not that expensive. But a couple more subways for some links that need more volume would probably be needed.
Not necessary. You can walk a few hundred meters to your end destination. It's actually good for your health.
Not to mention, laying tons of tracks on streets for a light rail network is a thing that's been around since before personalised cars.
