I'm guessing an engineer named it the German equivalent of "pre-crash" sound, then someone in marketing decided that "pre-safe" sounds better. It may be better to call it "foreplay" sound, since if you ever hear it you're probably screwed.

Some technical disciplines use "safe" as a transitive verb meaning "to make it safe", either from damage or from damaging other things.

I've seen it most often in rocketry contexts - you "safe the rocket" in an aborted launch scenario so it won't go off accidentally, etc.

  "It is a good idea to add a safety release valve to your launcher. Sometimes it is important to abort a launch and safe the rocket after it has been pressurised." http://www.aircommandrockets.com/rocket_launcher.htm (Google "safe the rocket" for occasional other examples.)

So the PRE-SAFE sound means the sound is to "safe your ears" before the crash, making them safe from damage.

I wish fire alarms did this for half a second before blasting your tympanic membrane with an ear-splitting noise. Residential ones are bad enough, but the ones in offices are the worst.

That's a good idea! I bet if someone were to develop a residential smoke detector that did that it would sell well. (Especially if it had other compelling features like a 10-year battery.)

FYI - The 9V Lithium batteries last that long.

Well, they do need to overcome my noise-cancelled high-volume drown-out-coworkers music...

Listening to high-volume music every day can damage your hearing.

Listening to my coworkwers can be worse!

Unfortunately they don't devote any attention to longevity or serviceability. But yes the safety features are excellent.

Mercedes is actually known for their engine longevity, reliability and serviceability. Yes they have more issues with technology than other cars, but that's because they use more and newer technology than cheaper brands. [1] [1] https://www.osv.ltd.uk/are-mercedes-benz-reliable/

They were, before their cars were filled with gadgetry. Can you find a 5+ year old Merc without something broken? The first buyer or lessee has moved on to something newer by then so nothing has to be designed to last long.

Could this be used by the military to lessen combat injuries?

Less combat would lessen combat injuries even more.

And lessening car crashes would help with injuries far more than pre-safe sound. Unfortunately both are innevitable.

Good to know! We bought a few with integrated 10-year batteries from Home Depot a few years back, but I didn't realize you could get regular lithium 9Vs that last that long in a smoke detector now.

Still I doubt if it is actually justified, considering in India a similar size car is perfectly serving its purpose with a 60 to 70 HP engine.

The same reason Apple Doesn't sell an iPhone Zero in the US with a single core processor and 64MB of RAM. The US is a mature product. High end brands don't sell sub-lowend products.

But then it means that Americans are overpaying by buying capacity they don't really need. This is something I'm always wondered at, as in the 3rd world even well-off people try to minimize their expenses.

The Mercedes is known for being more expensive than most, but in most cases, it's worth it, not only for the luxury, but for the extreme attention to detail they put into safety. For example, when you get into one, it will adjust the tension of the seatbelt automatically to be ideal for each passenger. And of course this pink noise. And a ton of other little things that cost extra that most people will never notice.…

I was recently in the market and was impressed by the amount of safety features available in modern models (my old car being a 2011 model). In the luxury range everything had automatic braking for rear-end collision, back-up collision prevention, 360 camera, lane-keeping assist, etc.. (albeit often as part of a pricier package). I'm sure many other brands have similar features too. A couple days after I got the new c…

These features are also coming down in the prices ranges now as well. I recently bought our first car, a 2017 Suzuki that cost us $8,000 used (closer to $14,000 new maybe?)

It has the birds-eye view 360 degree parking camera (and curb view), forward collision auto emergency braking, lane departure warning and it'll beep at you when the car in front starts moving after a red light and you're too engrossed in your phone to notice.

I lost most of my hearing in my left ear in a head-on collision with a drunk driver. No other injuries. The audiologist said that my eardrum was in the kind of state you usually only see in battlefields from exposure to large explosions. People are always surprised when I tell them this was my only injury, and as a result I've always wondered how common this type of injury is with vehicle collisions. This is the firs…

I’ve taken up wearing earplugs while driving. I also work in a noisy environment, and it occurs to me that the road and engine and wind noise is probably loud enough to have a negative impact on hearing over time. Less so in newer cars, but both mine are over 10yo. Also, in the event of a collision I’m protected.

Fantastic, someone driving a deadly vehicle responsible for 40,000 deaths every single year, and now they can't even hear anything either.

Hey, but as long as you are ok, right?
