This will go over like a wet fart in church:

Electric vehicle warning sounds are sounds designed to alert pedestrians to the presence of electric drive vehicles such as hybrid electric vehicles (HEVs), plug-in hybrid electric vehicles (PHEVs), and all-electric vehicles (EVs) travelling at low speeds. The U.S. National Highway Traffic Safety Administration issued its final ruling in February 2018, and requires the device to emit warning sounds at speeds less than 18.6 mph (30 km/h) with compliance by September 2020, but 50% of “quiet” vehicles must have the warning sounds by September 2019.[3] The European Parliament approved legislation that requires the mandatory use of “Acoustic Vehicle Alerting Systems” for all new electric and hybrid electric vehicles within five years after publication of the final approval of the April 2014 proposal to comply with the regulation.[4]
