The camera becomes blurry and shaky - completely useless. It's a common and well known issue if you happen to mount the phone on your handlebars (do NOT do this). I have several friends who've had this happen in the last year. All the way up to 12 Pro.

I wonder. Can this same happen on a dashboard mounted phone in a car?

Cars are better insulated and vibrate less in the first place. But if you do offroad and gravel with lots of vibrations, I think it might increase the risk.

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.

Before someone asks if this could be "fixed": This is a desirable trait. It improves the frame stiffness of the vehicle, resulting in better handling.

Refreshing to see a link to F9 on HN.

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.

Ignore the motorcycle bit completely and just think physics

You could trigger this on any oscillating “body” if that body is oscillating at a certain frequency and amplitude combination.

It just so happens motorcycle engines produce that combination. There would certainly be others. tHe sustained nature of the shaking would also be cause for concern but I didn’t see any mention of duration in the support article

Potentially? But it’s a known issue only to motorcyclists and (pedal)cyclists. idk why Apple is saying this is due to engine vibration but I think it has more to do with hard suspensions.
