The National Highway Transportation Safety Administration (NHTSA) is investigating whether hybrid-electric and electric vehicles from 1997 to present should have external speakers installed for pedestrian safety. The investigation was officially opened on January 27th, according to Teslarati.

In 2018, Federal Motor Vehicle Safety Standard (FMVSS) 141 passed. This new safety standard required electric vehicles and hybrid-electric vehicles with a weight of 10,000 pounds (4,536 kilograms) or less to have a pedestrian warning system (PWS). A PWS is an external speaker on the vehicle that plays a sound when the vehicle is traveling at low speeds. This ensures pedestrians can hear vehicles if they’re nearby.

Sounds of the PWS While Driving

EVs and hybrid-electric vehicles can be extremely quiet, especially at low speeds. EVs can go unheard when approaching stop signs, crosswalks, and intersections, especially if there are other environmental sounds as well.

In July 2022, a petition was received by the NHTSA that urged the organization to require all EVs and hybrid-electric vehicles to have external noisemakers installed on them. Any vehicles without them, regardless of their manufacture date, would be considered to have a safety defect, according to the NHTSA’s Office of Defect Investigation.

“The petitioner asserts that hybrid and electric vehicles to which the standard does not apply should be found to contain a safety defect. In support of the petition, the petitioner includes findings contained in a bill introduced in the House of Representatives in 2009, the Pedestrian Safety Enhancement Act of 2009, H.R. 734, 111th CONG. (2009).”

The passing of the Pedestrian Safety Enhancement Act of 2009, which was signed into law by President Barack Obama in 2011, says all vehicles should have a feature for “alerting blind and other pedestrians of the presence and operation of nearby motor vehicles to enable such pedestrians to travel safely and independently in urban, rural, and residential environments.”

Should the NHTSA agree and side with the petitioners, roughly 9.1 million cars across multiple manufacturers would be affected. These include Polestar, Tesla, Toyota, Nissan, BMW, Honda, and more.

Tesla’s Pedestrian Warning System

Tesla started installing their PWS in their vehicles in 2019. This was a mandatory change for Tesla, as both the US and EU passed laws requiring electric vehicles to make some kind of noise due to their quiet sound levels at slower speeds. The noise is played continuously until speeds of 19mph are reached, per the US regulation.

“The Pedestrian Warning System (PWS) is an audible tone played when the vehicle is moving slowly (up to 19 mph) in either Drive or Reverse,” Tesla said at the time in a memo to staff. “The sound is played via a speaker mounted in the front fascia and alerts nearby pedestrians of the car’s presence in low-speed situations.”

Tesla started manufacturing vehicles for this long before the regulations went into effect. Tesla enthusiast and YouTuber DÆrik noticed the speaker grill on the front underside of his 2018 Performance Model 3.

PWS Also Adds Boombox Feature

In classic Tesla and Elon Musk fashion, they went the extra mile and added some playful goodies for owners to get a laugh out of. They called this new feature “Boombox,” which allowed sounds to be played using the vehicle’s external speaker. For example, while in park or drive, the vehicle was able to fart, play music, and any noises the user uploaded.

Unfortunately, the NHTSA thought this was distracting and banned the feature while in drive. It's currently available in most regions around the world while the vehicle is parked.

If NHTSA requires Tesla to retroactively install PWS in their vehicles built before 2019, owners will at least have the Boombox feature to look forward to. During Tesla's 2022 holiday update, Tesla also added the ability to use Emissions Testing Mode through the Tesla app. If your vehicle is equipped with the PWS, then the vehicle will play the farting sound through its external speaker. Otherwise, it will be played through the internal speakers - which isn't quite as much fun

Tesla appears to be planning an ambitious project to build a private 5G network. This initiative would revolutionize connectivity for its vehicles and the robot, Optimus, as well as any other plans the company is likely to develop in the future.

Innovative Job Posting Reveals Big Plans

Although now removed, a recently spotted job posting for a Cellular Systems Integration Engineer on Tesla's career page shed light on the company's intentions. The role demands expertise to elevate Tesla's vehicle and Optimus robot connectivity, promising to push the boundaries of low latency and high data rates.

Tesla's journey from 3G to the anticipated 5G upgrade will bring about ultra-reliable communication and high-speed data transfer, crucial for over-the-air software updates, autonomous driving features, and real-time data analytics. These communications could be product to product, such as vehicles communicating with each other or with other products such as Optimus. However, the job posting also talks about products being able to communicate with Tesla’s internal 5G network. It’s not clear whether the private network would be internal such as at a Gigafactory, or a broader network out in the world.

The Strategic Role of Private 5G Networks

Deploying its private 5G network, Tesla aims to create a seamlessly connected environment in its manufacturing facilities, research labs, and outdoor spaces. This infrastructure is not just about enhancing vehicle connectivity; it's also pivotal for the operational efficiency of the Optimus robot in various scenarios, including warehouse operations.

Tesla's foray into private 5G networking places it in an advantageous position in the automotive and tech industries. This strategic move aligns with the global trend towards adopting private 5G networks, which promise to revolutionize industries with their reliability and speed. Tesla's efforts to develop a private 5G protocol stack that integrates with any cellular infrastructure globally will set new industry standards.

With 5G, Tesla vehicles and Optimus robots will benefit from significantly reduced latency, offering under 5 milliseconds compared to the 60-98 milliseconds of 4G networks. This technological advancement is expected to enhance the functionality and responsiveness of Tesla's products, paving the way for advanced autonomous driving capabilities and efficient robot operations.

Tesla's interest in developing a private 5G network is a logical step. By building an infrastructure that supports the fastest connectivity standards, Tesla is preparing for its vehicles and laying the groundwork for sophisticated robotics applications.

Italy has been discussing with Tesla about potentially establishing a factory producing electric trucks and vans. This information came to light in an Italian media outlet, Il Sole 24 Ore, which reported that the Ministry of Business and Made in Italy (Mimit) spearheaded talks to secure Tesla's investment.

Tesla and Italy: A Strategic Dialogue

Since last summer, Italy has broadened its industrial horizons by engaging in talks with Tesla, alongside negotiations with prominent Chinese manufacturers such as BYD, Great Wall Motors, and Chery Automobile. Notably, the discussions with Tesla have centered around producing electric commercial vehicles, highlighting a departure from conventional car manufacturing and reflecting the evolving demands of the global market.

Under the leadership of Minister Adolfo Urso, Italy aims to invigorate its automotive sector by encouraging the presence of multiple manufacturers. This approach is designed to stabilize the national components sector, which faces challenges due to the shift towards electric vehicles. Italy aims to produce 1.3 million vehicles annually, including a significant contribution from a new yet-to-be-determined manufacturer.

A Geopolitical and Industrial Balancing Act

Italy's engagement with Tesla occurs amidst a delicate phase of negotiations with Stellantis for increased vehicle production within the country. This strategic dialogue with Tesla, alongside discussions with Chinese competitors, is a pivotal element in Italy's industrial and geopolitical maneuvering.

A multipurpose van is the next logical step for Tesla to produce once the less expensive next-gen platform is released (code name Redwood). However, engineers seem to be busy perfecting the next-gen Roadster, and the van has had little discussion. Given the company's leaks, if a van were in the works, you would think we would’ve heard about it. Perhaps this is the nudge Tesla needs to get the van into production.

As Italy endeavors to become a key player in the electric vehicle industry, its negotiations with Tesla signify a promising development. The possibility of Tesla establishing a facility for electric trucks and vans in Italy underscores the country's commitment to sustainable transportation and positions Italy as an attractive destination for automotive innovation.
