I was young. My mother could not hear it and thought I was just being annoying. This is several decades ago, now I can barely hear my turn signal blinker and am preparing to emulate my father's practice of driving a few miles with his blinker on after signalling a lane change.

One thing that can help is pressing the turn signal lever with less force than is needed to latch it. This should cause the indicator to flash three times and then stop. It’s an operating mode I wasn’t aware of for decades.

Not all cars do this, german car feature? (only VW's I've driven from 2000's onward seemed to have)

In those cases, you just hold the signal to the point of switch activation, then let go when done.

I think "comfort turn signal" is a feature all newer (2000+) cars should have. I haven't found one from that age that didn't have this feature.

2002 Mazda Miata and 2002 Toyota Camry XLE don't have this. I couldn't find anything about it being a regulation, seems to have become common toward end of that decade though.

I've had this feature in Chrysler, Ford, Honda, and Hyundai cars ranging in year from 1995 to 2021.

Works on my 2009 Honda and 2017 Chrysler.

My 2012 Vauxhall Astra does this.

It's been too long since I posted to edit this, so I'll reply to my own comment: something else my car does that isn't at all unique and some people might be delighted to learn (if theirs supports it too), is that if you hold down the unlock button on the keyfob (rather than press it), it lowers all of the electric windows, and if you hold down the lock button, it raises them. Useful if you left one of your windows open and it starts raining; you don't need to go to the car to shut the windows.

Another German car feature. There's some regulation in the US that requires them to be coded not to go back up (but you can change the coding with a cable). Family has an X5 that will go down as you describe but not up for those reasons.

My Kia has it as well.

Mazda too

Long ago I made a conscious effort to turn off my blinker when I’m halfway into the next lane and now turn signals are like entirely subconscious for me.

I've been trying to break that particular habit, on the grounds that most of the purpose behind a turn signal is to indicate entry into a new lane rather than departure from the old one. Not sure what the law says about that, though.

Both equally important.

If the signal is used sufficiently in advance (aka "indicating" your lane departure),

and you're not cutting things so close you need a blinker to fend off cars behind,

then there should be no problem turning it off once half of your vehicle is in the lane.

I've been tested to 22+kHz, autistic, and older. It was the worst era.

Some of the awful roars of noise I've heard while older people called me a weirdo. CRTs, early checkout scanners, some audio systems.

And back when "as seen on TV" electronic dog whistle trainers were all the rage? Torture.

A few years ago I went to the beach. The place I was staying at had a CRT television. I tried to use it once. I have no idea if something was wrong with it, but it was loud enough to cause pain. Once I turned it off, everything was quiet again and the pain was gone.

I'm 30 with mild tinnitus and listen to music too loud but I can still hear CRT whine too, go figure.

Wait, people regularly just don’t hear it?

You'll usually stop hearing the CRT whine in your 20s, 30s if you're lucky. It's at nearly 16KHz and the highest frequency you can hear always drops as you age.

Of course, these days people also regularly don't hear it since CRTs are nearly all gone.

Even back in my youth and early adulthood, there was a wide variation on how loud CRTs were between models and individual units. There were some that were close to silent for me, while others were very noticeable.

37 here. Definitely still hear if the CRT is on. I have a few 8bits.

Most of us don't.

The signal is at a frequency of one cycle per line-second, but there's an idle period while the beam goes back up to the top where it still cycles so the actual frequency will be a bit higher than a simple lines/frame * frames/sec calculation would indicate. Even for broadcast TV that was beyond what a lot of adults can hear (but a lot of kids can, as plenty of posters in this thread have said.) I want to say 15.7khz but I certainly won't swear to that. As your resolution goes up the frequency will go up so some people would be able to hear what resolution a monitor is set to.

Yeah, that one's a bit lower. 15.625kHz or 15.75kHz depending on your region.
