I keep my iPhone in my jacket pocket and use the bluetooth module on my helmet. I also have a Garmin GPS on the handebar of my touring bike, although in 2021 you can get GPS built right into the bike's instrument panel. (To be fair, my most preferred navigation method on long trips is to tape a piece of paper with handwritten notes to the fuel tank anyway.)

This is how I drive cars long distance (but without taping it to a fuel tank), smartphones are handy for quick short navigation, but I feel uncomfortable trusting it for longer journeys - I want to know where i'm going and how i'm going there.

This is well known.. planning navigation by reading maps engaged our brains actively.. following navigation basically makes us dumb spatially

Noise cancelling headphones can negate it but it could damage a phone? This seems more like the place for people to gather and say "I don't like motorcycles because loud." Which is fine, but let's not really say it's related to the post.

You have a reading comprehension problem. The one situation is where a phone is in very close proximity or even mounted on the bike, the other where there is multiple 10's of meters between my seat the motorcycle, as well as me being inside a house.

It's more that it is hard to pick out your main article-related point from the bulk of the comment, which is just a complaint against a neighbor. I'm not against your frustration or in favor of your neighbor.

So it sounds like you're saying that if your neighbor's bike can shake your walls at that distance, then the same sound could/would damage the phone at a smaller distance? I'm not confident either way on that, other than believing that resonance probably plays a large part when it comes to the acoustic vibrations. Apple also did not say that the phones would be damaged just by being near the bike, so they may not be affected by it (or Apple is omitting that part, which wouldn't surprise me)

Rigid car phone holders routinely fall off for me thanks to frequent potholes in India. The ones with adjustable shoulder and elbow joint shake violently but don't dislodge, as an inadvertent feature. Its time for new generation of phone mounts.

Dashboards are not bolted directly to engines. The issue is that motorcycle parts are more directly connected to the engine. Sportbikes normally use the engine as a structural member, bolting all the other bits and pieces to the engine block. So vibrations through motorcycle handlebars and such are more intense than those on the dash of even an extreme muscle car.

Refreshing to see a link to F9 on HN.

Yes, but the proximity is such that the soundwaves themselves could conceivably vibrate the case enough to do damage if it is in a partially enclosed space and facing out (because that way it gets pressure from only one side, essentially a reverse bass speaker).

Nah dude, you’re really reaching. So now loud noises break the iPhones camera?

It's not a bad hypothesis, but would Apple have withheld that info if they were already advising people of the danger of direct mounting? They could just advise people to keep their phones inside a padded box or something of the sort.

To clarify, on most motorcycles the fuel tank is directly in front of the rider's pelvis.

Presumably the steer bar is detached somewhat as it turns the front wheel which is sprung? Also, I can imagine that the vibrations also make it tiring to hold. So just like a proper sander can be used without getting tired arms from the shaking.

Buy a gopro then?

dharmab is correct, the use on dirt bike handles is common, doing things a GoPro can’t.

On the camera side, a GoPro is fixed-focus and has a fixed aperture of (usually) f/2.8 and varies the exposure, shutter speed and frame rate unless set. There is no autofocus to damage. However, there are also no navigation apps for GoPro.
