    Electric cars: New vehicles to emit noise to aid safety

    https://www.bbc.com/news/business-48815968

    Will putting a baseball card in the spokes work?

    New electric vehicles will have to feature a noise-emitting device, under an EU rule coming into force on Monday.

    It follows concerns that low-emission cars and vans are too quiet, putting pedestrians at risk because they cannot be heard as they approach.

    All new types of four-wheel electric vehicle must be fitted with the device, which sounds like a traditional engine.

    A car's acoustic vehicle alert system (Avas) must sound when reversing or travelling below 12mph (19km/h).

    The EU says the cars are most likely to be near pedestrians when they are backing up or driving slowly, although drivers will have the power to deactivate the devices if they think it is necessary.

    The charity Guide Dogs - which had complained it was difficult to hear low-emission cars approaching - welcomed the change, but said electric vehicles should make a sound at all speeds.

    Roads minister Michael Ellis said the government wanted "the benefits of green transport to be felt by everyone" and understood the concerns of the visually impaired.

    "This new requirement will give pedestrians added confidence when crossing the road," he added.

    From 2021 all new electric cars must have an Avas, not just new models.

    The government has announced plans to ban new petrol and diesel cars and vans being sold by 2040.

    Alternatively-fuelled vehicles made up 6.6% of the new car market in May, compared with 5.6% during the same month in 2018.

    At Tesla's 2013 shareholder meeting, CEO Elon Musk said the ideal low-speed sound system would be able to identify and target pedestrians.

    "I think the sensible, ideal thing long-term is to have proximity sensors that direct a pleasant sounding noise in the direction of where somebody is walking — so therefore, it's the least amount of noise, and it's not annoying, and it's only going to where it needs to go. That's what I think is the right long-term solution," he said.

    Elon Musk's ideal low-speed sound system may not be the best one

    Edmunds said Musk's idea may be more trouble than it's worth. It would require the development of reliable software to detect pedestrians, which could replicate the difficulties auto companies face with autonomous vehicles, which use a suite of sensors and cameras to interpret their surroundings.

    "That sounds more expensive, frankly," Edmunds said. "It seems like that just adds unnecessary complexity."

    Surprised they don't put brake sensors on them, so when something pops out.... oh, wait........
