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.

Wouldn't this, in the end, make cars have to shift to a lower gear, thus keeping about the same RPM, and thus eating about the same amount of fuel, which results in about the same volume of the sound produced by the car?
This feels like a terrible fix.
afaik most of the sound comes from the tires, not necessarily the engine or the exhaust. obviously not the case for every car, but for most commuter cars it is. the faster the tires are rolling, the louder the sound.
i think at higher speeds the wheel and road noise drowns out the engine noise, but at lower speeds its the engine, especially during acceletation.
in the region of 20-30mph i'd think the engine is probably the louder part.
While this is a point the naysayers brought up, the slower speeds during the trial period reduced accidents, the severity of accidents, and the slower speeds encouraged more foot and bicycle traffic on those roads
Do you know when the trial period was?
I ask because the Welsh government apparently carried out a pollution test to justify the lowered speed limit on the main road into the capital, but did it during the Covid lockdown, when most cars were off the road.
That's not how cars work, they definitely don't use the same fuel in different gears at the same RPM. See this Wikipedia article for a discussion of speed vs fuel economy.
And as pointed out by the the FAQ, that's doesn't not factor in acceleration:
Most cars, at least in NA, have excessively large engines. It is crazy that we use 2L engines to carry one person around, when their own legs would suffice.
Studies have been done on this, and lower speeds correspond with less noise pollution.

A lot of cars can cruise at 20-25mph just idling in Drive, foot completely off both gas and brake. The RPMs don't get much lower than that.
My forester, when the engine is cold, will idle at about 25 mph :v, it calms down once it's warm, but still. I wouldn't be driving around with my foot on the brake
if the cars are designed to use the same fuel for less useful output power, then they're very badly designed.
i'm sure they might be less efficient in terms of miles per gallon. but they surely can't be so bad as to waste absolutely more fuel at lower speeds.
if they are, fuck them.
People have a misconception that cars waste more fuel at lower speeds, but it's really due to where the lower speeds are happening. Fuel is mostly wasted due to constant stopping and acceleration, like in a city environment with traffic lights and stop signs. On a highway, it's actually more efficient because you aren't stopping so often.
