Electric vehicles are most certainly not silent. At car park speeds they make as much noise via various fans, pumps and tyre noise as most modern internal-combustion engine vehicles. At high speeds the wind and tyre noise is comparable to any car. And like so many other issues surrounding the EV, this “problem” was addressed years ago. The EV1 had a back-up warning, as well as a pedestrian alert that could be activated by the driver when needed.
