Sounds weird

The latest example of good intentions gone awry;

Electric cars, which have soundless engines, would need to make noises to let pedestrians know they’re near under a U.S. proposed rule released Monday.

Sounds would need to be detectable when vehicles are traveling slower than 18 miles per hour so electric and hybrid-electric cars can be heard by bicyclists and pedestrians, particularly the visually impaired, under the U.S. National Highway Traffic Safety Administration rule.

Above 18 mph, cars make enough noise that they don’t need artificial sound....

So now manufacturers will have to spend millions, and add those costs to the price (already higher than the quality of the vehicle would dictate).  We could always offer another tax rebate to have the taxpayer cover it.
