I own Model Y and "High-Pitched Whining Noise while Accelerating" is my favorite sound. I hear it pretty much every day and it never gets old. I wonder if other EVs make that sound, but it's just incredible.
I kinda want the ability to have that piped into the car. Make it sound like an R/C car.
background: I had a model 3 for a couple of years and now have a Y ( no longer have the 3). The 3s are insanely quiet. The Y is ok but has a whistle at certain cruising speeds (90-100km/h). But when they are supercharging they are both ridiculously loud. Like having AC on full bore. Also starting a charge makes the most bangs and pops, regardless of the charger type. I just finished a 2000km drive and slept in the ba…
The next Model 3 ("Highland") uses laminated glass in the rear windows, whereas the current one just uses it for the front. Should be the quietest yet.

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.
What's the UX reason to use a chime rather than an (customisable) announcement? I suppose I'd get used to the alarms if I used the car but all of them on a page is confusing.
Confirmation tones are used to convey that the car registered a deliberate user action (e.g. a button press). For example whenever you press the unlock button on your key fob, it would quickly become annoying if the car announced "The car is now locked". In the case of confirmation, you know what the tone is signaling, because you just performed the action to create the tone (and don't need a lecture about it). Mildl…
Ha, I'm having flashbacks to my neighbor's old Chrysler New Yorker (from the K car era). "The door is ajar, the door is ajar." And couldn't just say it was open, that doesn't sound fancy enough.
> the first time you hear it, the tone will be seared into your memory
Indeed, the joke is that the Tesla alert tone causes PTSD after you hear it the first time.

Supposedly one of the arguments for lane splitting in California was the propensity for bikes to overheat out here when stopped in traffic. My 650 did not have a fan but it did a good enough job heating up my crotch to a nearly unbearable degree on a hot day without it.
I have certainly experienced overheating due to traffic on my air cooled bike. Now I am thinking about adding a fan to my oil cooler that would either be on a switch or even on a proper thermostat.
I hope one day, Tesla would use these sounds to troubleshoot and perform preventative maintenance.

My understanding is that high-end residential heat pumps (e.g. Mitsubishi HyperHeat) will do this at lower temperatures as well. If the temp drops into the zone where the heat pump starts losing effectiveness (which on such systems is still pretty low, supposedly mine provides the full heat rating down to around 0F), they can run the blower motor in a less efficient regime to supplement the heat pump with a bit of re…
It would really be nice not to have to go in and try to imitate the sound to my mechanic, and it would help give me an idea what the repair ought to cost.
I've spent thousands of dollars on misdiagnosed (or misrepresented) "repairs," and it would be great to get a diagnosis from the mechanic, look it up, and say, "No, it doesn't sound a thing like that."

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.
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…
