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.

Trams are the future!
Agreed. I love trains and it frustrates me to see them bungling the implementation. When they try, they always seem to make the same mistakes trying to bring it to my area.
To see meaningful ridership out here, the train needs to go fast enough to negate the penalty you get at the other end when you have to go from the station to your destination. They wanted to run them at ~55-70mph here, with a few stops between major cities, to parallel a freeway that is 65-75mph. Drive 1 hour (1:10 with parking) or spend 2 hours going to the station, riding a slow train, then going from the station to where you are going? I hate cars, but as someone who only gets a handful of hours to myself after sleep, work, and chores, I'm going to save my time and pick the car. If they ever build the train, as it is planned right now, it'll just be another commuter train that's only really used at rush hour when the roads are jammed rather than an all day all week car replacement solution that I can ride to Sunday night dinner at a friends house as easily as a 6am meeting.
/un-requested rant
@njordomir @Sanctus The safe money is it will also run too infrequently to be a good replacement. Adding 'time waiting for train' to the picture for trips outside of 6~9am or 3~7pm and officials wonder why services aren't well used.
Interestingly, a similar problem as with bike infrastructure. The infrastructure isn't useful until a lot of it is built and it connects everywhere (and timetables get shorter for trains). The infrastructure won't pass public opinion until it's proven to be useful to people. I will always vote yes on funding these projects even if I think they will bomb because it puts us a little closer to the peak of that hill. Its still frustrating though. We could easily do like we did with the freeways if we just decided it was worth building.
@njordomir But all of it is network effect in action: the incremental value of each piece is related to how many pieces already exist.
The worse part is, what infrastructure does get built isn't used because it's mostly useless, and people use this lack of use as justification for not building more.
My city has been pushing through improving the biking infrastructure for a decade now.
People have been bitching about it from day one. They bitched even more as the first lanes were going in, as they were "useless" and went "nowhere"
They've continued to bitch about it every year, every construction project.
But now, we have a highly interconnected network of bike lanes (most protected) all around town and they're getting heavily used.
People still find reasons to bitch about it like it's slowing down traffic by narrowing roads or lost parking spots or whatever, but the "it's not useful" stuff has stopped.
My current push is bike infra for kids to get to school, parks, community centers and libraries. Roads aren't a safe for them and they can't drive themselves.
@njordomir If we have to order the changes that are needed: good zoning laws should come first (and are free/revenue raising), next comes PT (the most expensive thing), and third is cycling infrastructure/modification of roads.
When you do it in that order you need a lot less dedicated cycling infrastructure as you can close lots of roads to through traffic and drop speed limits. That is because you've got PT that is a strong option so people don't need to drive nearly as much.
Your math doesn't even add up but, obviously we should also have more time off lmao
the best way to improve public transportation is if the public uses it….
It has to be competitive with cars for people to switch. Everyone cares about their wallet and their time. Cheaper transit that is faster than cars will attract more ridership.
Maybe build ebikes instead of EVs? Then you'd need about 1/50th to 1/100th the copper.
Don't forget tramlines.
Metal Theft sector booming. Meth stocks are up.
They'll start mining landfill for metals and probably plastic soon enough. Air it out, wash it, get the metal and plastic, don't worry about that other in the air/water, that's a future poor person's problem.
metals, sure. The problem with plastics is that plastic is not plastic, it's a plethora of different chemical structures. Very difficult to recycle some of them, even if sorted.

No one uses pennies anymore… Just sayin’.
So it's time to a coup d'etat on Chile AGAIN!
Or more child slavery, maybe? Sorry, that is for batteries.
for god "Capital"
I always find it ironic that people with the most money are always the hungriest for it. Their entire lives revolve around it, and they are willing to pay any other price for it. They will kill ecosystems, pollute everything and even destroy societies for it.
Power does not corrupt, it only attracts the corrupted
This can be improved if all vehicles moved to a full 48v architecture. Substantially less copper that way.
@NotMyOldRedditName @Hypx I'm not against it, but I didn't think most of the copper in a modern car / EV was in the LV supply wiring, so such a change would be more in the range of a 10% reduction?
It's somewhere between 100 and 150lbs saved per car.
There's a lot of copper in the wiring harness and it's most of the weight. It's also a reduction in the plastic around the wires, the other weight contributor.
Edit: For EVs anyway, my bad. Probably less copper in non evs, but still a lot.
@NotMyOldRedditName Are power carrying wires the bulk of the wires in a car?
And by power I mean more than 5W where wire gauges start to get serious at 12V. An indicator LED is technically needing power, but not enough that wire gauge bulks up.
Also just for reference, this is what Tesla's double redundant 48v etherloop cable looks like, instead of those chonky wiring harnesses
Edit: Just to clarify here, I think I made an assumption about the double redundancy. The cable runs in a loop around the car, and if any cable gets cut, it can still reach the component via the other direction (A<->B<->C<->A). I think I just assumed the 2 wires in the image were redundant. It could be that different data is flowing over both strands and those are not for redundancy. Maybe those are for each direction as well? One cable sends data around the car clockwise, the other counter clockwise?
@NotMyOldRedditName yes, everyone is heading towards data busses over central control of everythieg. Telsa is further down that road because they started development after everyone knew they needed to go that way, but the established OEMs have longer pipelines and it takes a lot to change things.
That said, busses have security issues, stealing a car from the canbus behind the headlight isn't good.
Wiring harnesses from traditional automotive companies are quite long. This is quote from Ford's CEO
"“We didn’t know that our wiring harness for Mach-E was 1.6 kilometers longer than it needed to be. We didn’t know it’s 70 pounds heavier and that that’s [cost an extra] $300 a battery,”"
4km is normal
https://q5d.com/escalating-function-dilemma/
"Some modern vehicles contain close to 40 different harnesses, comprised of roughly 700 connectors and over 3000 wires. If taken apart and put into a continuous line, these wires would exceed a length of 2.5mi (4km) and weigh approximately 132lbs (60kg). Five years ago, vehicles had 25% less circuits than today’s cars. Five years from now, that number will increase by more than 30%. "
@NotMyOldRedditName yes, but that is tangential to my point (and your original point). The total length of wires doesn't tell you if they are power or data.
Fair, but you can't do 12v ethernet like they've done with 48v. The cables would be too big
So unlocking 48v allowed the change which allowed lesser cabling.
Tesla claims it's 77% cable reduction and 50% copper.
Edit: also Teslas wiring harnesses have been smaller than industry standard for years. If others made the switch and moved to an etherloop as well, the copper savings would be even bigger than what Tesla experienced.
@LovesTha @NotMyOldRedditName @Hypx
Also, stuff like this. (I believe Tesla is going this route with its cheaper EV.)

@MrLee @NotMyOldRedditName @Hypx I'm surprised that an aluminium electric motor is such a novel thing.
@LovesTha @NotMyOldRedditName @Hypx
I heard an interview with the boss of that company, and he was asked why aren't others doing this? "Industry Inertia," he put it down to.
When supply chains, expertise, manufacturing machines, techniques, and decades of data on reliability and performance are established, it's hard to change all that inertia.
The first person to do it also incurs a higher upfront cost as there isn't the same level of scale to bring costs down.
@MrLee @NotMyOldRedditName @Hypx yeah change takes time, but there are plenty of peiple with knowledge of both magnet free motors and working with aluminium. But it feels like a development problem more than a research one.
Deploy the crackheads!
