Tesla Model 3 spotted with “pedestrian noise maker” ahead of NHTSA mandate

Published

It looks like Tesla may have already begun getting its newer manufactured vehicles ready for compliance with an upcoming National Highway Traffic Safety Administration (NHTSA) requirement for electric and hybrid electric vehicles to make noise when traveling at slow speeds. In a video posted by Tesla community’s resident DIY expert, Erik, or otherwise known as DÆrik from his YouTube channel, the undercarriage panel of his Performance Model 3 has what appears to be a speaker grill – the front paneling is adorned with a series of holes in a hexagonal shape. Once the paneling is removed, three mounting points are revealed to be molded into the same area, hinting at a future device to come.

The video was made in response to inquiries about a photo of the Tesla’s undercarriage posted to Erik’s Instagram account where someone noted the series of holes in the plastic panel below the front bumper. Tesla’s parts catalog doesn’t currently show the grill cutout, but As Erik notes in the video, he found a Model S diagram three years ago showing a layout including a future noise maker labeled “Speaker Pedestrian Noise”.

We’ve reached out to Tesla for comment about the new “speaker grill” found in the underside of the Model 3 and will provide updates as we receive them.

Blind pedestrians rely heavily on auditory clues to anticipate traffic patterns and know a vehicle is near, and that means the quiet nature of electric and hybrid vehicles at low speeds may pose a greater danger to them than traditional internal combustion engine (ICE) vehicles. Bicyclists and other pedestrians also utilize usual car sounds as part of their personal safety awareness, so there’s a population of travelers that could be significantly impacted by the influx of EV/HEV vehicles on the roads. The potential danger has not gone unnoticed by those in charge of public safety.

This concern was elevated to the federal level by the NHTSA, and the eventual result was a 2010 law (Pedestrian Safety Enhancement Act of 2010) requiring electric and hybrid vehicle manufacturers to install devices which emit noise while traveling slower than about 19 mph. Higher speeds have tire and wind noise that’s sufficient for pedestrian needs. The implementation rules were finalized in February last year, and manufacturers have until September 1, 2020, to be fully compliant, with half of the vehicles equipped by September 1, 2019.

While the proposal may not be popular with all parties involved, the NHTSA points to its October 2009 report entitled “Research on Quieter Cars and the Safety of Blind Pedestrians, a Report to Congress” as a primary basis for its rulemaking. In the report, the agency found an increased rate of accidents involving pedestrians with hybrid-electric vehicles compared to ICE vehicles in roadways and zones with low-speed limits, during the type of weather or any time of day. By implementing the rules as passed, the NHTSA expects to prevent 2,400 injuries and reduce the $250-$320 million costs which result annually due to limited ability to detect quiet EVs/HEVs.

Another coming requirement is that the noise emitted must be identifiable as a vehicle, a limitation that will likely only inspire creativity. If manufacturers want to take a fun route with the noise options, i.e, license the Jetson family’s flying car sound from Hanna Barbara as suggested by Erik, they’ll have to make sure it’s consistent among their vehicles – or at least consistent among package options. Also, drivers cannot be allowed to modify the sound themselves.

Manufacturers are free to modify the sounds from the factory end, though, an option Tesla’s CEO Elon Musk has previously capitalized on for other noise-centric features in the electric car company’s vehicles. However, letting drivers determine their car’s noise via app or button push is still in the air. The NHTSA will publish a separate document at a later date to determine whether driver-selectable sounds are a good idea, or at least compliant with the purpose of the law.

Tesla CEO Elon Musk has confirmed that the company will roll out a new feature for in-car Grok as it is rolling out to vehicles for the first time.

Grok was just recently added as a feature to Tesla vehicles within the past week, but owners are already requesting some small changes to make it more convenient to use.

Tesla debuts hands-free Grok AI with update 2025.26: What you need to know

The first is already on the way, Musk confirmed, as WholeMarsBlog requested a simple, but useful feature for Grok as it is used within Tesla vehicles.

Whole Mars requested that “Hey Grok” be used as a wake word, automatically activating the AI assistant without having to touch any buttons. Musk confirmed it is already in development and on the way to vehicles:

This feature is incredibly similar to that of “Hey Siri” with iPhones and other iOS devices. The phone will recognize your voice and hear that prompt, automatically activating Siri. Apple’s assistant will then perform whatever task it is asked to perform. It’s a simple but effective performance feature.

Grok is already getting its first reviews from owners as it rolls out to owners for the first time. It is a long time coming, too. Tesla has been hinting that Grok would be enabled in the vehicles for a while now, and it just started its initial rollout last week.

Grok is available in vehicles with the AMD chip and requires Premium Connectivity or a WiFi connection to use.

Tesla reveals key detail of Supercharger Diner, but it’s bigger than you think

Tesla has finally released one key detail about the Supercharger Diner, and it is bigger than what it appears at face-value.

Tesla has revealed a key detail of its Supercharger Diner as its launch date appears to be nearing, based on what we are seeing at the site currently.

The Supercharger Diner is located on Santa Monica Boulevard in Los Angeles and was first proposed as an idea by CEO Elon Musk back in 2018. Musk envisioned a drive-in movie-style 1950s-inspired diner that would feature elements such as servers on roller skates, large movie screens, and a menu inspired by classic treats from several decades ago.

A project that first broke ground in 2023, the Supercharger Diner has been in development for over two years, as Tesla performed demolition work at the site back in February of that year.

It has slowly moved forward, and drone footage shot this week seems to show things are nearly up and running. Musk even mentioned that he had eaten at the Diner Supercharger this week.

There are still details that Tesla has yet to announce and confirm. The most important thing is regarding the menu that will be served at the diner.

Tesla has not hinted at what it will be making for patrons at the restaurant, but Musk commended the food and said the diner would be one of the coolest spots in LA.

However, we now have details on another important thing about the restaurant: the hours.

Images taken by Aaron Cash of ABetterTheater.com show the diner will be open 24/7, as it appears on the front doors of the diner:

At first thought, it seems this will operate like any other diner, as many are open for 24 hours a day. Diners typically serve large menus with numerous options, catering to the tastes and moods of anyone who walks in.

People of all walks of life eat at diners, as the food is typically affordable, tasty, and available at any hour to serve those who are night owls or those who work non-typical schedules.

However, Tesla is a bit different, and it seems that this new venture into food service could eventually transition from human servers and cooks to robots, most notably the company’s in-house project of Optimus.

It is something straight out of a Star Wars movie. I can think of Obi-Wan Kenobi visiting Dex in his diner in Attack of the Clones to figure out where a poison dart was sourced from:

Eventually, Optimus will likely be working as an employee in the Tesla Diner, and 24/7 operation will be performed by the humanoid robot that aims to eliminate trivial tasks from humans.
