Another new crime!

It's already illegal for car drivers, but if you're on a bicycle,
it's now illegal to use a headset, earplugs or earbuds in both
ears while operating your bicycle.

It's in there - buried deep down within the wholly unrelated crap.

(11) Existing law prohibits a person operating a motor vehicle or a
bicycle from wearing a headset covering both ears, or from wearing earplugs
in both ears, subject to certain exceptions.

This bill would also prohibit wearing earphones covering, resting on,
or inserted in, both ears. Because a violation of these provisions would
be a crime, this bill would impose a state-mandated local program.
