on the radio

has the following ever happened to you?

You're driving down the street in your car, listenign to the radio, when you hear a siren. Your heart jumps and you start veering off the road, looking around for hte flashing lights, and you are cursing the drivers around you who are not reacting to the siren. Then you realize DUH it was sound effect on the ad playing on the radio.

Sometimes I hear a beep tone on radio ads that sounds just like my cell phone text message alert.

Since a huge number of radio listeners are listening in their cars, has anyone ever considered that context, and the potential dangers (well agravation anyway) when putting sirens in a radio ad? i doubt it.
