\"SYDNEY,

SYDNEY, AUSTRALIA – MAY 17: Detail of the charging point of the Nissan Leaf is displayed at the ‘A World Without Petrol’ art exhibition at Customs House on May 17, 2012 in Sydney, Australia. Designed by Australian artist James Dive and inspired by electric vehicles, the interactive exhibition of 40 recycled petrol bowsers converted into useful everyday items is intended to promote the Nisaan LEAF, the first mass produced 100% electric vehicle in Australia.

Electric vehicles must make noise to warn\u00a0pedestrians of their coming by 2019, U.S. road safety regulators said this week. And the\u00a0measure\u00a0is grist for\u00a0our mill here at\u00a0\u201cCars That Think\u201d\u00a0because Tesla Motors appears to be developing a robotic solution to the problem.<\/p>\n

The National Highway Transportation Safety Administration announced on Monday that noisemakers would be needed in pure electric and hybrid\u00a0vehicles operating at speeds under\u00a030 kilometers per hour (19 mph). At higher speeds they evidently make\u00a0their own noise,\u00a0thanks to resistance from wind and road.<\/p>\n

The first\u00a0clue to Tesla\u2019s plans,\u00a0Electrotek\u00a0<\/em>reports, is the statement Tesla\u2019s Elon Musk made at a press conference back in 2013.\u00a0\u201cI think the sensible and ideal thing long-term is to have proximity sensors that direct a pleasant sound in the direction of where somebody is walking,\u201d Musk said.\u00a0The second clue came earlier this year in the form of\u00a0blueprints\u00a0apparently leaked\u00a0from Tesla. Clearly visible are structures labeled \u201cpedestrian speakers.\u201d<\/p>\n

It\u2019s unclear whether regulators will accept Musk\u2019s proposal to\u00a0beam noise with\u00a0laser-like focus to spare the ears of the unthreatened. On the other hand, just broadcasting the noise takes away a key EV marketing advantage:\u00a0silence. (Except for the motorcycle market. Some fans of Harley\u00a0Davidson\u2019s iconic bikes have disparaged that company\u2019s planned electric version for its un-Harley-like purr.)<\/p>\n

Many\u00a0EV\u00a0motorsports events\u00a0already\u00a0require the noisemakers\u00a0to protect onlookers, photographers and pit crew. At this summer\u2019s\u00a0motor race at Pikes Peak, Colo., local stores sold\u00a0modified car alarms\u00a0to racing teams for just this purpose. The price: $8.<\/p>\n

Toyota, which inaugurated modern EV technology with its Prius hybrid, has supplied optional noisemakers for years. So has Nissan, whose Leaf was the first\u00a0mass-market all-electric car.<\/p>\n","protected":false},"excerpt":{"rendered":"
