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.

Škoda Storyboard

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.

What's your easy technical solution to improve common sense, then? Or is it the all time classic of "just improving society"? I'm all ears for your ideas.
