In emergencies people often evacuate by car, and lacking any access to emergency announcements can result in traffic jams mis-navigation, which ties up rescue personnel.

If you choose to die at home fine, but public roads are life-critical infrastructure. Guaranteeing everyone in the ensuing 'thundering herd' at least access to a basic AM/FM radio isn't too great a cost burden.

"Why do I need this radio, I don't use it" is a lot like saying, "why do I need this seatbelt, I never crash!"
