A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The most popular seem to be lighthearted clever little truths, hidden in daily life.

Here are some examples to inspire your own showerthoughts:

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. No politics
    • If your topic is in a grey area, please phrase it to emphasize the fascinating aspects, not the dramatic aspects. You can do this by avoiding overly politicized terms such as "capitalism" and "communism". If you must make comparisons, you can say something is different without saying something is better/worse.
    • A good place for politics is c/politicaldiscussion
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct and the TOS

If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.

Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report, the message goes away and you never worry about it.

So self driving car brands are currently in the process of offering subscription based self driving features.

Soon these subscriptions will be cheap enough for everybody to abandon public transport and get into their self driving cars instead.

This means that everybody will be in their cars and it will create the biggest traffic jam in human history!

And finally, self-driving cars will be totally safe and able to drive completely unsupervised! While standing still in traffic going an average of 5 km/h...

It will be beautiful (/s)

Traffic is massively impacted by people breaking after ending up too close to another vehicle. There are great demonstration videos in the late 90s / early 2000s demonstrating this. I don't anticipate me stating this fact to gain any support, because, you know, Lemmy says AI bad no matter what.

You're right: when traffic is at its critical density, that's often what triggers the shift from the free-flow regime to the congested regime. But just because you make computers drive the cars -- even assuming they did it perfectly without randomly braking, which they don't -- that doesn't mean it eliminates that flipping between regimes. At best, it might get you a little bit more capacity before hitting that critical threshold, but eventually it's still going to, and then something -- a squirrel darting into the road, a sunbeam glinting off something the wrong way and momentarily confusing the AI, a bump that disturbs the car just enough to make it slow down a fraction of a MPH, etc. -- is going to trigger that shift to the congested regime anyway.
