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)

I suppose self-driving cars could drive like regular cars on the small roads, but then go to big specialized highways where they can go full speed.

But that doesn't make sense anyway, because that would not save you that much time anymore. And in that case you could just have regular cars to drive to a station with parking and then take the train to your destination

We already have those big specialized highways; that's what freeways are. The trouble is, even if autonomous driving were capable of doubling the lane capacity (and IIRC the theoretical best case is actually less than that, closer to a 50% improvement), induced demand is still a thing. It maybe buys you a reprieve for a decade or so, but after that you're right back to "just one more lane, bro!"
