Installing an external speaker on an electric car to alert pedestrians and cyclists of its approach may create unintended risks, according to new findings. While the modification aims to improve safety by making the vehicle’s presence more audible, experts warn it could also mask critical warning sounds or lead to confusion in noisy environments. The potential trade-offs between visibility and auditory cues raise questions about whether such adaptations could inadvertently compromise safety rather than enhance it. Concerns have been raised about how these systems might interact with existing traffic noise regulations and pedestrian awareness programs.


Fitting an electric car with an external speaker for safety reasons turns out to have some potential drawbacks.
