This community exists as a sister community/copycat community to the r/fuckcars subreddit.

This community exists for the following reasons:

You can find the Matrix chat room for this community here.

Rules

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. 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.

  7. 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.

Most of the combustion products from gas are 'clean' - water and CO2. They don't contribute to particulate air pollution.

CO and NOx are output in much smaller quantities, and are contributors to air pollution, but not to particulate air pollution.

From the tailpipe, the only real particulate matter is a very small amount of soot, and this is a small fraction of the overall combusted mass - engines are designed to minimize soot in order to increase performance and fuel efficiency.

Tires and break pads, in contrast, simply abrade into the air essentially in their entirety.

Yea totally, that's why I suggested the rewrite that I did. It seems a bit nuts to exclude CO2 from the phrase:

In California, sources other than tailpipes are the dominating source of traffic emissions"

... when CO2 emissions are like ending life on earth as we know it.

A lot of things are ending life on earth as we know it. CO2 emissions are just one of them. It's like the stupid argument that plastic bags are fine because a hundred plastic bags emit less CO2 than one cotton one... But plastic bags aren't even close to being a significant element of CO2 emissions. It's a waste problem.

In this case, it's saying that particulate pollution won't magically get better by switching to EVs. The research shows that that's true.
