Škoda DuoBell: A bicycle bell that outsmarts even smart headphones - Škoda Storyboard

Pedestrians wearing headphones are exposed to an increased risk of accidents. In an effort to reduce collisions with cyclists, Škoda Auto, in collaboration with scientists, introduces an innovative bicycle bell whose sound can penetrate even active noise cancellation systems. In doing so, it helps prevent injuries to both pedestrians and cyclists.

Over engineering in real life, solving lack of common sense by introducing a solution where the cyclist is paying.

I think the solution is nice for sure, but solving the wrong problem.

The presentation looks like marketing overkill, their solution looks pretty simple. It‘s just two trills „Trillerwerk“ bells combined. It was the standard in Germany until the late 1990s https://youtu.be/-mW7dWHDivo
