mtbc | Noises on the radio while driving

Many in-car entertainment systems can reproduce sound rather well. Recently I was driving on the highway and I heard a strange sort of regular metallic knocking so I wondered what mechanical problem could have developed with the car to cause that. It turned out to be some irrelevant sound effect on the part of the radio program I was listening to: if I recall correctly, I surmised that it was the ticks of a clock before an election or referendum comes or we all get nuked or immigrants overrun the country or whatever. I was reminded of a program I used to listen to back in Ohio, aimed at commuters at rush-hour, which at one point would play the sound of numerous car horns. What idiocy: if we are in our cars then we rather need to be able to respond quickly to real car horns so it would help enormously if these fake ones wouldn't keep crying wolf. It would please me if the producers of radio programs were to be a little more mindful of this issue, especially when targeting what appears to be named drive time.
