In the past, sirens howled to warn the population against floods, large fires or chemical accidents. Today, however, there is no extensive warning system in Germany, as most sirens were dismantled after the Cold War. Researchers of the Fraunhofer Institute for Technological Trend Analysis INT in Euskirchen want the population to be warned by car horns in the future.
