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.

Since much of the noise pollution from cars comes from tire noise, I doubt EVs will reduce noise pollution that signifcantly.
It's not tire noise I'm hearing in bed at 1am while some yahoo is treating residential roads like a racetrack.
That is because many cities/politicians refuse to enforce reasonable noise limits on automobiles. It should have never been legal/normalized to have exhausts loud enough to need hearing protection while outside of the vehicle.
That shit ain’t legal, it’s just not enforced.
Legal where I live, and in many states too.
those ppl will create noise at whatever cost lmao, I bet they'll start attaching external speakers at some point to compensate for the lack of engine noise
Near motorways where they go high speed the reduction will be negligible, but is material around lower speed streets.
Something not mentioned is the significantly reduced brake dust as most EV braking is regenerative.
I see this argument a lot about EV's being heavier. And while it is true (for now) the actual weight difference is fairly nominal when comparing two popular closely spec vehicles.
Curb Weight Toyota Camry 3310 lb. Tesla Model 3 3582 lb. +272 lb.
The report goes on to note that pm10 is still reduced in heavier EVs with a smaller tradeoff for increased pm2.5. There are nuances sure, but I still interpret this as a net positive on particulate matter and a step in the right direction. That is something we should not discourage in a world that is still struggling to stop pumping carbon into the atmosphere. Fuck cars, but let's try to make incremental improvements where we can.
Abstract: Assuming lightweight EVs (i.e. with battery packs enabling a driving range of about 100 miles), the report finds that EVs emit an estimated 11-13% less non-exhaust PM2.5 and 18-19% less PM10 than ICEVs. Assuming that EV models are heavier (with battery packs enabling a driving range of 300 miles or higher), however, the report finds that they reduce PM10 by only 4-7% and increase PM2.5 by 3-8% relative to conventional vehicles.
Is this really substantial? With a skilled manual driver or a clever automatic gearbox, the majority of braking should be engine braking. It seems to me that regenerative braking is typically replacing what would be engine braking, the unplanned stops still use friction brakes.
Regen braking can be significantly stronger than engine braking. Unless your battery is at 100%, it can essentially replace all friction braking outside of emergency stops.
Noise pollution is a function of speed.
At low speeds, it's mostly engine noise. At highway speeds, it's mostly tire noise.
Many city streets have near highway speed limits or designs that easily allow cars to reach near highway speeds.
