The sound of a teenager driving dad’s midlife crisis just moments before smashing into the side of a building
I didn’t hear a corvette?

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…
0F ? That can't be right?
My Mitsubishi gives heat to around -31F (MSZ-RW Sumo)

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.
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…

>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…
Such a slow warmup is probably also bad for your engine (the oil will be super hard to pump around so you'll have very little lubrication and very high oil pressure until it warms up a bit) so that block heater may well be useful in more ways than one. 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…
It's astounding just how quiet EV's are; they can make you hyperaware of other noises (hence why this page exists).
Is this universal? I've driven the Rav4 Prime and Ioniq 5 extensively and neither made weird sounds.
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…

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.
The fan is triggered by a relay, triggered by the ECU, which uses coolant sensors (the thermostat sensor that is iirc not always the mechanical thermostat) to adjust when to cool the radiator. That temp is much higher than the ambient air will ever get, so if the fan comes on after the car is turned off then either it was just about at the temp that would have turned on the fan, or something could be slowly going wro…
With carburettor fed engines it is sometimes advised by the manufacturer to allow the engine to idle for some time after running it at high RPM. This is because the effect of heat soak can be significant enough to boil all the fuel off in the carb, making the engine hard to restart when hot.
