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:
- Both “200” and “160” are 2 minutes in microwave math
- When you’re a kid, you don’t realize you’re also watching your mom and dad grow up.
- More dreams have been destroyed by alarm clocks than anything else
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title
- 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
- Posts must be original/unique
- 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.

Manual driving will go away at some point. And fully autonomous vehicles would be electric, so no noise increase.
Once autonomous vehicles reach a critical mass, there won't be a real need to own one and auto insurance premiums will skyrocket since human drivers would be the highest risk.
The government probably won't need to intervene to kill human driving on public roads
Plus the number of vehicles in existence will dramatically decrease, thus lowering total pollution from manufacturing and maintenance.
The fact is that humans are awful at driving; it's one of the leading causes of death. A computer that doesn't get tired, intoxicated, or distracted with 360° sensors reporting a great many times per second will be significantly safer than a human.
We're not there yet, but companies like Waymo are making significant progress.
At low speed, most of the noise an ICE car produces is the engine. At high speeds, most of the noise is the tires on the road. At high speeds, electric and ICE cars are equally loud. At even higher speeds, they're even louder.
Electric vehicles have to artificially add engine noise so people can hear them...
Compared to ICE vehicles, they're silent. Whenever hybrids came out people kept getting hit because they couldn't hear them coming.
At low speeds, yes. They're just as loud at high speeds because the noise comes from the tires, not the engines.
