As he alludes to, this is different on Teslas. Where in an attempt to save a few bucks on a simple sensor they’re using “machine learning” to detect rain with the front-facing camera and it doesn’t fucking work.

NO SENSOR

ONLY CAMERA

The camera is many sensors.

You can overload anything by tasking it to do too much.

To be fair, a few dollar sensor would also require a harness, space on the windshield, some computing power, and a bunch of wiring.

They have a history of being cheap, and it’s worth it to make it work, but it’s quite an exaggeration to say it’s just the sensor they’re saving money on.

The acknowledgement that actually reading the freaking manual is important is too real.

Was trying to change the windshield wipers on my car last year. Front was trivial but the latch on the rear was just complete insanity. Ended up watching two different youtubes for slightly different years before realizing the manual “might” cover this. And it had a BEAUTIFUL diagram showing exactly how to disengage and reengage that latch.

“reading the manual” has become a True Concept for me. Like a big part of life that most people are ignorant or just unaware of. Once upon a time, you kids, there was only manuals. That’s all we had to figure out how to get the doowhacky to go in the whatsits.

Once upon a time, you kids, there was only manuals.

Then the manuals turned to shit, and we turned to just fumbling along because it was pointless to look in the manual.

Then came along the web, and we could search for other people’s answers.

Then for some reason, manuals really improved. I’m shocked at what manuals are like today (especially for cars).

As someone who has avidly been reading manuals since the early 90s, car manuals have always been pretty good. Home audio/video equipment has also had great manuals over the years too. I don’t recall a time these turned to shit.

Motherboards / BIOS documentation comes in dead last, and has always been shit. Dozens and dozens of proprietary settings that are not described by the manual nor the built in help, and there’s only conjecture online. At least now the English is mostly correct, but they’re still very bad at describing what niche settings do.

I had issues replacing the wipers too on my Kia, and couldn’t even find info in manual regarding this.

After an hour of fighting and trying to replace the wipers in down position, I realized I need to life up the hood and work from under it >.>

“Light changes speed” ???

permalink

Yes, what we call the speed of light is really the speed of light in a vacuum. When light passes through a medium like water or glass it travels slower. That causes the light to be refracted which means that it changes direction slightly based on the energy of the light (color) and the refractory index the material. Glass will refract a red laser by a certain amount while water will refract it by a different amount.

Fun fact, because different colors refract differently, when you shine a white light through a specially shaped piece of glass called a prism, you will see a rainbow pattern.

Also a gas! Astronomical spectroscopy is fascinating.

“The star radiates at [these] wavelengths meaning it has [this] composition, after the light bounces off/through the planet we see <these> wavelengths, meaning it has <this> composition.”

Yes? C is constant and light travels at C in a vacuum, but lights speed is different in other media.

OMG thats crazy! I just started driving with a learners permit last month and it was raining on basically every drive here. I was wondering constantly, how the car knew pretty much exactly when it should wipe! I debated of sending it as a video idea to TC as it is right up his alley. Well I didnt need to! Gonna watch it right now.
