Emergency Vehicle Audio Mute
I thought that it might be a good idea that all emergency vehicles (police/fire/ambulance) should be fitted with an encrypted transmitter that mutes audio devices in surrounding cars when close. So receiving triggers are built into car audio devices and personal ones such as iPODs that mute when emergency services are close. For example if a police chase is taking place nearby and person on a push bike for example is being deafened by their personal audio device it gets muted so they hear the siren...and dont cross roads etc...
Reward: Just high level recognition of me if this is a good idea and works...lol
