re: Kia Seltos windshield distortion is causing me extreme eye strain. EDIT : Resolved So I have faced a somewhat similar problem and had to research the topic after my doc explained to me that all patient complain of this for a month and none, not one, will believe the explanation so he just focuses on saying he's fixing it till a month passes by and then Pt stops complaining and even says it's great.
Offcourse, I feel bad in a way that we humans will refuse to believe someone with a different experience than us. I mean the OP perfectly trustworthy guy with experience of 4-5 Lac Kms driven (am just about 2.5 Lac km now) because we have never noticed this problem !!
Makes me realize how all the women might feel who don't complain about harrassment from bosses because this is exactly how we will respond - by offering different explanations - anything except the actual experience, because we don't 'think' it's possible
#Long post warning
So I have noticed similar issues in almost all, equipment that's meant to add-on/fix some human sensory capability. It's really bad in the beginning but goes away in few weeks/months in a pretty unbelievable way if we stop to think about it. I'll give 2 examples first then explain:
If anyone you know uses hearing aids, try them for a moment (check its not too loud to make you deaf or something)- even the best ones will have atrocious sound quality, not at all what you hear normally, no low freq /bass, huge noise, all mid to high frequencies in some other pitch/freq that we are used to, some voices from 3-4 rooms away & some inaudible right in your room etc.
Obviously, it's because all our tech evolved over a few hundred years at best, is still very primitive compared to biological things evolved over a billion years (with the test pilots in a few billion beings, bot a few hundred or few lac that wecan teat anything on)
The surprising thing is this: that's exactly what the person wearing those buds felt initially but after a month or two (ears will take a month + / eyes a week or two) s/he can hear & enjoy the lowest freq thumping bass & crystal clear high frequencies and NO noise. Because? The brain has adjusted to interpreting those sounds the way it needs.
Same thing with specs / glasses. It'll be normal in 2 weeks but the first few days the same thing you show about the scooter back handle is what it looks like for some things(not for everything. Only stuff like steps or road potholes - things your brain focusses on to guage depth position etc as its important for not falling. Other things are probably showing up weird too but it's not important so it's not rendering that with any accuracy and mostly just generating a virtual outline for the peripheral vision. Only if it moves it will suddenly measure stuff and draw a more accurate graphic.
The same glasses will become perfect in few weeks and that's because the brain has adjusted to the signals and what they mean so it draws pretty pictures for you regardless of the sensory inputs from sound or light which are anyway in electrical signals and have to be interpreted - it's not really light or sound going into your brain!
While ear corrections are easier to see as unbelievable stuff, specs are so common and in use for a decade plus for most adults so it's not easy to experience. Most of us have settings for 4-5 different specs that the brain can switch as per which one you are wearing. Also visual disturbances it will be able to fix as you move your head or eyes or walk around since angles will change and it knows how that thing looks from 100 angles.
But the effect of specs is still very very evident to anyone wearing them for the first time.
Wear someone else's specs with very different powers or different spherical corrections and u will see it. Keep wearing for 2 days and you will see it all looks normal now - even though out of focus.
The random errors/disturbances can be fixed by the brain quickly but not an effect which is through out the lens - so blurry image won't be fixed without a long time of use and even then to a small extent.
On fact if you Google you can read about the experiment where they put on glasses on volunteers that show e erything inverted. The people are initially unable to even walk as stuff is inverted ie their legs & floor is visible on top and the ceiling fan or roof on the bottom. They can't take off the glasses. In two weeks they can see normally every thing is the right way up to them !
BUT that's not the crazy part. Now their glasses are removed. Ans they see everything inverted with their normal eyes and can't even walk !! Takes two weeks for them to start seeing right side up again.
I had researched this when I got hurt and needed an ear operation but had to wait a year for that. So doc got me a cic or invisible hearing aid which sounded useless to me and I kept going back till he smiled and told me every single patient does this and there is no way to make them believe the above explanation so they know to just tinker a little with the settings and just ensure 1 month of use at which point patient will stop complaining and in another month or two almost all of them will call and say what a brilliant quality of sound and how were they managing without it. If patient had it in only one ear while other is mostly normal they will now complain that they want in other ear also ! Because the volume is higher so brain starts preferring these signals to interpret and not so much the normal ear. In fact in most cases they will put it in both ears because of this (and because sound is delayed by a tiny millisecond going through the rar bud so distance estimation by brain using TOF times from both ears will be messed up a bit so Pt.cant make out direction. Will always think his mobile is ringing when it's clear that sound is coming from somewhere else like a TV.
So now the last point, why would you not have noticed in other cars ?
I would like to generate some data if you can drive a few other cars NOW, at this point of time. AND not the cars owned by your friends n relatives that you have driven earlier. But cars of some other friends that you have not driven earlier. (I don't mean like u have driven creta earlier but that you drove Mr XYZ'z car earlier few times)
And it's perfectly fine NOT to believe this explanation - it's not necessarily correct, just one possible option.
Besides I did worse -
I kept thinking that the doc is just trying to sell substandard stuff to me for making money and this is probably local market thing he's put in a top brand's box etc. And when he was my school friend and has never ever done any such thing.
And everything he explained or I researched kept supporting this theory of mine till after 2-3 months I listened to very track - money for nothing - and thought the bass is so much better in this ear !
#Long PS: if still unconvinced:
In fact all artificial prosthesis and vaccines and artificial organs etc work like this - its the magical ability of your body to adapt to that crude solution that makea it work flawlessly, it's not like we have made something comparable to a body part.
Or that a vaccine has a magical ability to fix any disease - it's just an advance signal to warn the body to do its unbelievable magic before the actual disease coming in.
It's the same with Elon Musk's neural implants or all other machines to read brain signals - we pass on some shit signals as a visible thing on screen so you can see it and then your brain learns how to send a signal that can be seen in a certain way on the screen.
It's not the machine learning what we are thinking, it's just us learning how to think so that the machine moves in certain way.
Here's how his monkeys play video games by just thinking :
So they give a monkey a simple video game with a joystick. He learns to play that in some weeks.
They attach neuralink type sensor on his head (it has some antenna to read all type of elec mag signals) the machine starts matching random stuff between joystick & brain reading and gets some basic idea of what to read and what to ignore.
Then they disconnect the joystick and connect the machine in its place to tge video game.
Monkey still uses the joystick, though it's not connected. But the machine tries to move the joystick based on brain signals. It's able to just barely move the joystick, not at all with the fine control of actual joystick.
Monkey gets frustrated and keeps trying and it's brain slowly learns what type of signals move the joystick in what direction and to what distance and at what speed. Just like it learn to use joystick.
In a few months Monkey is playing just by thinking and they remove the physical joystick now.
