Drivers May Choose Electric Car Alert Sounds, US Proposal Says

The NHTSA is now proposing drivers be able to select an electric-car alert sound at speeds under 18.6 mph. "NHTSA wants the public's opinion 'on whether there should be a limit to the number of compliant sounds that a manufacturer can install in a vehicle and what that limit should be,'" adds CNET. From the report: As of this month, automakers are required to equip 50% of their "quiet cars," which applies to silent electric vehicles, with an alert noise at low speeds. The rules, first brought about in 2010, have been delayed for years, but come 2020, every quiet vehicle will need the alert mechanism. Regulators concluded cars make enough noise from tire and wind noise to forego the alert above 18.6 mph (that's 30 kph in case you're wondering why so precise a figure). Think of the sound as a gentle reminder when strolling through parking lots with cars backing out of spaces and crawling through the area. It's nice to hear a car approach, and something we take for granted with internal-combustion engines. NHTSA said the alert will help prevent 2,400 injuries annually.
