People "roll coal" it because it is kinda amusing to do it, and it is a middle finger towards people they perceive to be preachy.

I accidentally "rolled coal" in my 90s Landrover because I was in totally the wrong gear going up a steep hill. It was amusing in the way of "oh shit! I kinda just blew a load of black smoke in the driver face behind me".

Obviously, I don't do this deliberately.

> how (US) universal

I praise you for not defaulting to US-defaultism, which is quite common on HN, but this really seems to be universal. There are also regulations like this in Scandinavia, France, Germany is talking about it.

Australia banned phones in schools 1-2 years ago and it's been widely recognised as a huge success. I think banning social media like facebook/tiktok/etc for kids would be a huge benefit as well. Leaving just IM/group chats for kids to directly talk to each other without scrolling a feed of ragebait and ai slop.

You probably won't have much to worry about until you have to decide whether screen time for your kid (at age 3-4) is a reasonable trade-off for you and your partner to have peaceful time to yourselves. Then it'll rear it's head again, after lulling you into complacency, when the kid is middle school age and all their friends have smartphones. Then you have to decide whether the convenience factor (for you) of your kid having a device is worth the trade-off of... them having a device.

Fwiw, my older two are 14 & 16 and we still use device control software on their phones and laptops. The younger of the two complains a bit periodically but the older one just accepts that it's the way it is and gets on with his life [most of the time].

I personally advise you not to let your young kid get into e-gaming. Things like Fortnite, Roblox and Minecraft are gateways to increased device usage, and the benefits are (again, imho) not remotely worth it nor irreplaceable by much healthier alternatives.

Fun tidbit: my 8yo has a Kindle Fire and we've let her have Netflix & Disney+ installed on it. She also uses the Kindle & Libby apps to read voraciously, and Khan Academy for math. When she watches streaming media, though, she frequently watches it on mute with subtitles. That shocked me to see, and I asked her about it. She's 100% cool with that and appreciate the "privacy" of being able to watch things without other people meddling in her business. Shrug.

We got by just fine during the school day for decades (centuries?) before smartphones existed, and we can continue to do so without them.

Because social media sites like Facebook literally said they're going to make the world better, by connecting more people and empowering more ideas.

It was all bullshit of course, but people did believe it, myself included. Just 15 years ago the outlook of social media was much more optimistic.

America has an entire political party who runs a party line that unregulated businesses will naturally do what's "best" because of "free market mumble mumble". They even sometimes outright insist that "best" in that context means "best for humans and society", and that any attempt to constrain that will be Communism and cause all of society to collapse.

>What's best for society is a collection of rational, intelligent, and accountable adults.

That same party insists that you should be able to choose to enroll your child in a school that does nothing but teach weird christian doctrines, and outright lies like "Evolution is controversial" or "Continental drift is not proven" or "The USA is a Christian country". They demonstrably want to be able to direct my tax dollars to these institutions, based on their choice.

Everyone should spend time checking out what the tens of millions of self reported fundamentalist "Christian" americans pay money for. There is an entire alternative media economy and it is horrifying. It exists to reinforce tons of outright false and delusional narratives, like an imagined persecution complex against christians.

If you think those tens of millions of Americans don't have power or sway in this country, they are literally the reason why visa and mastercard keep shutting down porn businesses (the higher fraud claim is just false and probably a lie, ask me how I know!) and the current House majority leader is their guy, as well as Trump's previous VP, as well as maybe technically JD Vance, as well as like Joe Rogan, who insists that AI is the second coming of christ because it doesn't have a mother, just like christ. Not joking, that is a real thing that Joe Rogan has made millions of dollars saying to over 20 million people. Oh, and at least one Supreme Court Justice.
