It's astounding just how quiet EV's are; they can make you hyperaware of other noises (hence why this page exists).
I hope legislation gets enacted that will make it illegal to blast artificial "exhaust" noises from EVs. Not like cops will actually enforce it, but one can still dream...

Text would take a lot longer to convey information than a short chime. You would also have to localize all the sounds.
"TERRAIN, TERRAIN! whoop whoop PULL UP!" -- the makers of the Terrain Avoidance and Warning System (TAWS) thought that this extra information was useful. Maybe the timing is different or maybe it's just cultural.

I can see, and yet I've been scared more than once by an unusually quiet car behind me.
“Cabin Noise during Acceleration with Ludicrous Enabled” was by far the most interesting
Feels like a good opportunity to in addition to having the normal system diagnosis, have a process that listens to the sound the car makes and recommend bringing it into the shop if the sound sounds weird or off.
You basically call a number and then press a button on the appliance and it produces a sound that tells the customer service what's wrong.

I always thought about this growing up. How the engine’s heat is used directly to heat the cabin and there is no heater. Also my gaming PC in the winter. It feels like free compute given I’m heating anyways.
> Also my gaming PC in the winter. It feels like free compute given I’m heating anyways. Totally. If it's cold and you have an idle rig, you might as well use it to run a crypto miner before reaching for an actual heater.
Today I learned. The Tesla owner's manual has alt descriptions for its images. They're not good alt descriptions, but they are there. In fact, it is one of the most screen reader accessible manuals for any device I've ever seen, most are some weird PDF abominations where all the button names are replaced by their unlabeled icons. Even devices made specifically for the blind have these issues sometimes. This? This is…

A gasoline based ICE is so incredibly inefficient it needs to shed heat or it would melt down. It makes more heat than that it makes motive power (the thing it is designed to do...). A 50 KW engine makes 200 KW(!!) of heat (at full throttle). Most of that heat energy exits the system through the exhaust gases but there is plenty that gets stuck in the body of the engine and you need to remove it from there somehow be…
>Some diesels got so efficient though that they needed an extra in-line heater to have enough heat for the cabin in specific operating domains I live on the top of a hill, so the first seven minutes or so of me driving anywhere is coasting at minimum engine power. Once air temp gets below 10C it's a long, slow painful wait for the vents to start blowing warm air. Especially unfortunate when you're waiting for the def…
You may want to look into oil that flows better at low temps in winter based on what temperature your engine eventually reaches when it is fully warmed up. There is a good chance that your engine will work better with different oils for winter and summer, also if you have an older car you may get some mileage out of blocking off a piece of the radiator.
This one is pretty cool and definitely surprised me. > Motor Humming or Whirring when Navigating to a Supercharger … > In some circumstances (such as cold weather), it is normal for the motor(s) and components to make noise, such as humming or whirring as it generates heat to warm the Battery. Super cool that the motors can be used for things other than moving the vehicle. It reminds me of how ESCs for RC vehicles us…
I have a relatively analogue car (Subaru BRZ) and there are times when you shut it off on a warm day and then randomly about ten mins later a radiator fan kicks on. I guess it's to help cool down but I don't remember exactly what the manual says. Basically it's cool how cars do things largely on their own sometimes to stay within certain parameters.
If it happens a lot (when turned off) I'd think about having an inspection done. Worst case scenario, engine ends up overheating, warps or explodes, and you need a new one. Coolant system is one of those "oh shit" systems that you need to pay close attention to.
