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.

Do horns and bells really prevent accidents?

In order for e.g. a horn to work you need enough time that the driver processes the situation and decides the horn will communicate something AND enough time for the pedestrian or whatever to process that and react to it. Generally it's a lot easier just to press the brake, and more importantly be travelling at a speed and in a manner where the brake is sufficient.

Structurally, we'd be much better off reducing conflicts between the different tiers of users. I.e. properly segregated infrastructure for each class of vehicle.

A car company wanting to divert attention away from the carnage cars cause. Seems a bit suspicious no?
In Skoda's defense, it has a long tradition of making bicycles as well
