Electric Vehicles & Loud Pipes

Based on sales trends and environmental necessity, electric vehicles (EVs) are the future. But one concern of increasing EV use is the potential effects on pedestrian safety.

This has led to requirements that EVs generate some form of pedestrian warning noise when operating at low speeds where wind noise is negligible.
