Tesla has detailed the addition of its latest safety feature that comes standard with the new Model Y. It is a feature that has been in development for several years and aims to assist in saving lives while also enabling other safety features.

Within the past few years, Tesla has been developing an in-cabin radar that was aimed at detecting humans left in the vehicle that typical cameras would not detect. It was a feature that was initially developed to save the lives of children, who die a handful of times each year from being left in cabins without air conditioning.

Teslarati first reported on the development of an in-cabin radar system several years ago through Federal Communications Commission (FCC) documents, which showed Tesla was hoping to gain approval for a wave sensor that would detect heartbeats instead of relying on cameras.

The company has started using the in-cabin radar system with the new Model Y, which has been available in the U.S. for several months. Tesla has released the new Model Y Owner’s Manual online, which gives us a first-hand look at the details it released on the various advancements it has made with the newest version of the best-selling vehicle in the world.

As shown above, the Model Y’s new cabin radar is located above the rearview mirror and behind the ceiling gear shifter buttons.

Tesla describes its duties:

“Cabin radar can detect the presence of people inside the vehicle and use the measurements to determine occupancy. Cabin radar supports certain vehicle and safety features, including driver detection, seat occupancy, Occupant Classification System (OCS), and auto parking brake engagement.”

Interestingly, Tesla has added that it will be able to enable auto parking brake engagement, a great feature for when someone exits the vehicle. In the past, we knew it would handle driver and occupant protection, but we did not recognize its value as a way to enable a parking brake.

This week has been a tour de force of Tesla Optimus demonstrations. But even with the humanoid robot’s already impressive capabilities, CEO Elon Musk dropped a comment that truly made Optimus even more exciting. 

Inasmuch as Optimus today is likely one of the most advanced humanoid robots in the industry, it is still nothing close to what Tesla really wants to create.

Optimus Demonstrations

Optimus’ demonstrations this week caught headlines because they showed the humanoid robot performing impressive dance moves. Initially, a video posted by Elon Musk on social media platform X showed Optimus dancing while being tethered to a cable. A follow up video upped the ante, with Optimus performing actual ballet moves without any support.

Comments from Tesla Vice President of Optimus (Tesla Bot) Milan Kovac revealed that the humanoid robot’s movements were fully learned in simulation and zero-shot transferred to real without extra training. Elon Musk later joked that he would be accompanied by a troupe of dancing Optimus robots at the 2024 Tesla Annual Shareholder Meeting.

Not Even Close

But in another follow-up comment on X, Musk clarified that while Optimus is already impressive today, it is still very far from its planned final form. This was quite surprising as the humanoid robot is already in initial production at the Fremont Factory. Even in its current state, Optimus also looks production-ready. Elon Musk even noted that Optimus robots are just walking around Tesla’s factories today around the clock, charging themselves as needed.

With this in mind, one could wonder what Optimus’ final form could really be like. While the humanoid robot’s current iteration is already pretty sleek, perhaps Tesla is still developing Optimus until its appearance could mirror the robot’s static display model that the company showed off back in 2021. That Optimus model featured very human proportions and joints, making it look more like an android from a sci-fi flick than a humanoid robot with obvious mechanical parts.

SpaceX is positioning its Starlink constellation as a viable GPS alternative. In a letter to the Federal Communications Commission (FCC), SpaceX stated that it could leverage Starlink satellites for next-generation Positioning, Navigation, and Timing (PNT) solutions.

GPS has been run through a single provider in the United States, the Defense Department. The FCC intends to use Positioning, Navigation, and Timing (PNT) solutions to complement GPS technologies. In its letter, SpaceX highlighted Starlink’s potential to deliver PNT services alongside its broadband offerings in its letter to the FCC.

“As the Commission identifies specific actions to contribute to the whole-of-government PNT system resilience effort, one opportunity stands out as a particularly ripe, low-hanging fruit: facilitating the rapid deployment of next-generation low-Earth orbit (‘LEO’) satellite constellations that can deliver PNT as a service alongside high-speed, low-latency broadband and ubiquitous mobile connectivity,” SpaceX wrote.

SpaceX also emphasized its ongoing work to integrate PNT into its cellular Starlink service, which is expected to be launched with T-Mobile in July. The private space provider also stated that Starlink satellites already operate independently of GPS. This lays the groundwork for resilient PNT delivery across authorized frequencies, SpaceX noted in its letter.

“SpaceX has also been actively working to integrate PNT solutions into its direct-to-device commercial service offerings. In so doing, SpaceX can advance the Commission’s goal in this proceeding to maintain American leadership in next-generation PNT services both here at home and in over 130 countries it serves around the world.

“SpaceX looks forward to playing an integral role in creating a more robust, resilient, and secure PNT ecosystem for Americans and people around the world,” SpaceX noted.

SpaceX also advocated for a “technology-neutral approach” to GPS alternatives in its letter, while critiquing EchoStar’s unused 2GHz spectrum for mobile satellite services. Meanwhile, Globalstar, Apple’s satellite provider, also pitched its services as a GPS complement, stating that its services “can function as either an alternative or a complement to GPS.”

“Notably, Globalstar’s satellites transmit outside of the L-band, which provides PNT users with added immunity from GPS jamming and spoofing. In addition, Globalstar’s satellite transmissions at 2.4GHz are stronger than GPS signals, bolstering resilience, performance, and reliability,” GlobalStar noted.
