This is true for any electronics with moving parts. Apple just decided to announce it.
If your camera has OIS/moving lenses, or if you have a mechanical hard drive, or if you have anything small that requires precision alignment, putting it on a vibrating surface is a bad idea.
Even high end camera lenses can have problems sitting on the floor of a car, an airplane, or being thrown around in unpadded container.

And as someone posted above, loud pipes are not proven to save lives and probably do nothing. As a former rider (briefly) who did post grad traffic accident research, the sound from loud pipes is directed backwards, not forwards. It is also low frequency, making it harder to locate. Even EMS systems which are high frequency and directed forwards have trouble projecting noise into cars for distracted driver.
If you think about it anecdotally, how many times have you "heard" a bike (or car) coming as opposed to hearing it passing? Its pretty rare. The only time it is useful is *maybe* splitting lanes in traffic at low speed
If you really want to save lives on a bike, drive responsibly, wear a full face helmet and a high vis vest, with a good light set up and DRLs. But those are often seen as "nerdy"
