That’s really only needed at slow speeds. At higher speeds the tire noise is enough. Even for most modern ICE cars, at higher speeds the tire noise dominates over the engine/exhaust noise.
Most modern ICE cars are still deadly-quiet at slower-speeds as well. Also, pedestrian safety is a weird context in which to be espousing “tire noise is enough for pedestrians, just gotta go fast”.
