American cars having their brake lights and turn signals be the same light is stupid and dangerous.

When changing lanes or turning you are supposed to use the turning signal before doing the manouver. The turning signal is supposed to warn other drivers that you are going to do something. It doesn’t make any sense to use the turning signal when already mid-turning or while already changing lanes. Many drivers don’t seem to know that.

Not voting doesn’t stop an election.

Things you will need to operate while driving your car shouldn’t have touch screen controls.

That we’d all be better off if we accepted our own fallibility. That we are not perfect little robots, and as a result more tolerance and forgiveness in the world is necessary.

8% of 50 is 50% of 8

Here’s one that’s not as consequential as other posts here. It’s not going to change the world, but would make things slightly better.

Split lock washers are worse than useless. They’re supposed to be a spring against the bolt to help resist it turning back out over time. They don’t. If anything, they make it worse.

Here’s a NASA publication on fastener design (because of course there’s a NASA publication on fastener design): https://ntrs.nasa.gov/citations/19900009424

The lockwasher serves as a spring while the bolt is being tightened. However, the washer is normally flat by the time the bolt is fully torqued. At this time it is equivalent to a solid flat washer, and its locking ability is nonexistent. In summary, a Iockwasher of this type is useless for locking.

This was published in 1990, but we’re still using this shit. Stop. There are many other kinds of fastener locking that work, like nylon locking nuts or threadlock, and we don’t need these.

That documentation is supposed to explain how a thing works to people who don’t know how it works. I know, sounds extremely obvious, but you’d be surprised how much documentation out there is written in a way, expecting you to already know what it’s talking about. No. I do not. It is the documentation’s job to explain ME what IT is talking about…

That other than a niche we specialize in, we’re pretty fucking dumb at everything else.

“Homeopathic” does not mean organic, or good for you, natural, wholesome, effective, or inherently safe to consume.

It is, in fact, a code word for no active ingredient.

How corporations use advertisements to influence how the media reports on their activities. Prime example is how BP ran all those “We’re Sorry” ads when they poisoned the Gulf of Mexico. They weren’t apologizing to the public. They were using the ads to pass bribes to the news agencies to make sure to give them soft coverage when they should have been ranking them over the coals.

That chiropractic care is not evidence based

The spices at the grocery store I’ve been going to for the past 25 years has had the spices alphabetized this entire time.

Edit, I misread the question but I’m not fixing my response

Perpetual growth in a finite system is impossible, and anything that relies on perpetual growth to function is doomed to eventually fail.

For instance: social services that rely on perpetual population growth (especially youth population; e.g. Japan/South Korea), companies that rely on perpetual increase in users (most publicly-owned companies; e g. basically every social media company ATM), industries that rely on perpetual advancements in technology (e.g. industrialized agriculture, which constantly needs new ways to fight self-induced problems like soil depletion and erosion), housing as wealth generation (to be a wealth generator it has to outpace inflation, but at a certain point no one will be able to afford to purchase houses at their inflated prices no matter how over-leveraged they get; e.g. Canada). [Note that these are merely examples where these issues are currently coming to a head; they are by no means special cases, they’re just in a more advanced state of “finding out.”]

In other words, a lot of the modern world, in both public and private sectors, is built around a series of ponzi schemes.

You cannot achieve any good by hurting people.

People are so convinced that if we’re more cruel to criminals, they’ll stop committing crimes, or if we’re harsher to workers, we’ll work harder, or if you’re tough on border controls, immigrants will go away. It does not work and it cannot work.
