Who knew, Tesla Autopilot has a human collision avoidance system

Published

on

Tesla released arguably one of the biggest over-the-air software updates in its company history when it introduced Version 8.0 with updated Autopilot in September. Not to be confused with the more recent announcement that new Model S and Model X vehicles are equipped with next generation “hardware 2” capable of Full Self-Driving, Autopilot under Version 8.0 leveraged two-year-old hardware to issue enhancements in drivability and safety through advancements in radar signal processing.

By placing more emphasis on input from the vehicle’s forward-facing radar, Tesla Autopilot was able to detect vehicle activity from two cars ahead and better react to sudden emergency braking events. A recent test using a Model X while trailing two vehicles – the furthest vehicle would simulate an emergency braking situation – demonstrated that Autopilot was able to automatically react to activity beyond what its human driver could see.

But how does v8.0 Autopilot fare against activity from a non-vehicle – let’s say, a human obstacle? Previous tests put together by Tesla owner and YouTuber KmanAuto attempted to see just that. Using a very trusting friend, Kman was able to demonstrate Autopilot’s lack of ability to account for pedestrians when it comes to emergency braking under version 7.0.

Back at it again, and with the same friend Mike Anthony, the duo staged seven separate tests to see how the latest Version 8.0 Autopilot, using radar-based technology supplemented by the front-facing camera, was able to handle situations involving a human obstacle.

Tesla Autopilot under Version 8.0 vs. Human (Mike)

Before we jump into the results of the various tests, we’d like to note that Teslarati in no way endorses or recommends this type of stunt, or any activity of similar nature.

We’ve provided the full video here with outcome of the results summarized below. Be sure to also check out the video from Mike’s perspective.

Test 1 – Tesla @ 20 mph vs. Human in middle of lane

Description: Vehicle was able to detect Mike and gradually come to a complete stop on its own with no driver input. Display did not show an object. No human collision warning appeared.

Test 2 – Tesla @ 20 mph vs. Human walking in front of the car

Description: Vehicle was able to detect Mike walking into the car’s path of travel and bring itself to a complete stop. As Mike walked backwards and away from the vehicle, Autopilot Traffic Aware Cruise Control (TACC) was able to keep its distance to Mike and proceed forward as Mike inched backwards.

Test 3 – Tesla @ 20 mph vs. Human walking from side of road in front of car and then off the road again

Description: Vehicle was able to detect Mike walking into the car’s path of travel and bring itself to a complete stop. As Mike walked off to the side of the road, TACC resumed.

Test 4 – Tesla @ 20 mph vs. Human walking in front of the car

Description: Same as Test 2.

Test 5 – Tesla @ 30 mph vs. Human jogging across all lanes in front of vehicle

Description: This is the first sighting of a human collision warning indicator. Vehicle detects Mike and attempts to hard brake“In the interest of safety I helped [brake] it, the car gave me a collision alert and it also applied the brakes.”, says Kman.

Kman indicates that the vehicle likely would not have stopped in time to prevent hitting Mike but it would have severely lessened the force of impact and possibly lessened the severity of  human injury.

Test 6 – Tesla @ 25 mph vs. Human walking in front of the car

Description: Vehicle was able to detect Mike walking into the car’s path of travel and bring itself to a sudden stop and avoid impact.

Test 7 – Tesla @ 35 mph vs. Human standing directly in front of moving car

Description: Vehicle was able to detect Mike standing before the car and bring itself to a quick stop though no visual warning was seen on the display. It would appear the human collision warning only appears with objects that are non-stationary and enter the vehicle’s path of travel.

Video of Test 7

Conclusion

The test demonstrates Tesla’s remarkable ability to continuously improve upon its Autopilot suite of features through changes to its set of algorithms driven largely by data collected through the company’s fleet learning program. The test is also significant in that Tesla was able to dramatically improve the safety on its vehicles – now capable of performing emergency braking events when a human is detected – purely over-the-air and with no hardware improvements whatsoever.

With Autopilot 2.0 consisting of seven more cameras and enhanced long range sonar sensors fed from billions of miles worth of driving data, it’s not a question of if Tesla can reach full Level 5 autonomy, but one of when.

The FCC just said ‘No’ to SpaceX for now

SpaceX is fighting the FCC for spectrum that could put satellites inside every smartphone.

Published

SpaceX was dealt a new setback on April 23, 2006 by the Federal Communications Commission (FCC) after the U.S. government agency dismissed the company’s petition to access a Mobile Satellite Service spectrum that would allow direct-to-device (D2D) capabilities.

The FCC regulates communications by radio, television, wire, and cable, which also includes regulating D2D technology that lets your existing smartphone connect directly to a satellite orbiting Earth, the same way it would connect to a cell tower.

Elon Musk’s SpaceX has been building toward this through its Starlink Mobile service, formerly called Direct-to-Cell, in partnership with T-Mobile. The service officially launched on July 23, 2025, starting with messaging and expanding to broadband data in October of that year.

It’s worth noting that SpaceX is not alone in this race. AT&T and Verizon have their own satellite texting deals with AST SpaceMobile, while Verizon separately offers free satellite texting through Skylo on newer phones.

The regulatory foundation for all of this dates to March 14, 2024, when the FCC adopted the world’s first framework for what it called Supplemental Coverage from Space, allowing satellite operators to lease spectrum from terrestrial carriers and fill gaps in their coverage. On November 26, 2024, the FCC granted SpaceX the first-ever authorization under that framework, approving its partnership with T-Mobile to provide service in specific frequency bands. SpaceX then went further, completing a roughly $17 billion acquisition of wireless spectrum from EchoStar, which gave it the ability to negotiate with global carriers more independently.

Starlink’s EchoStar spectrum deal could bring 5G coverage anywhere

This recent ruling by the FCC blocked SpaceX from going further, protecting incumbent spectrum holders like Globalstar and Iridium. But the market momentum is already in motion. As Teslarati reported, SpaceX is targeting peak speeds of 150 Mbps per user for its next generation Direct-to-Cell service, compared to roughly 4 Mbps today, which would bring satellite connectivity close to standard carrier performance.

With a reported IPO targeting a $1.75 trillion valuation on the horizon, each spectrum fight, carrier deal, and regulatory win or loss now carries weight beyond just connectivity. SpaceX is quietly becoming the infrastructure layer underneath the phones of millions of people, and the FCC’s next move will help determine how much further that reach extends.

Elon Musk talks Tesla Roadster’s future

Elon Musk confirmed the Roadster as Tesla’s last manually driven car, with a debut coming soon.

During Tesla’s Q1 2026 earnings call on April 22, Elon Musk made a brief but notable comment about the long-awaited next generation Roadster while describing Tesla’s future vehicle lineup. “Long term, the only manually driven car will be the new Tesla Roadster,” he said. “Speaking of which, we may be able to debut that in a month or so. It requires a lot of testing and validation before we can actually have a demo and not have something go wrong with the demo.”

That single statement is the entire Roadster update from yesterday’s call, and while it represents another timeline shift, it comes as no surprise with Tesla heads-down-at-work on the mass rollout of its Robotaxi service across US cities, and the industrial scale production of the humanoid Optimus.

The fact that Musk specifically framed the Roadster as the last manually driven Tesla is significant on its own. As the rest of the lineup moves toward full autonomy, the Roadster becomes something rare in the Tesla-sphere by keeping the driver in control. Driving enthusiasts who buy a $200,000 supercar are not doing so to be passengers. They want the physical connection to the road, the feel of acceleration under their own input, and the experience of controlling something with that level of performance. FSD, however capable it becomes, removes that entirely. The Roadster signals that Tesla understands this distinction and is building a car specifically for the people who consider driving itself the point.

The specs for the Roadster Musk has teased over the years are genuinely unlike anything in production. The base model targets 0 to 60 mph in 1.9 seconds, a top speed above 250 mph, and up to 620 miles of range from a 200 kWh battery. The optional SpaceX package takes it further, rumored to add roughly ten cold gas thrusters operating at 10,000 psi, borrowed directly from Falcon 9 rocket technology. With thrusters, Musk has claimed 0 to 60 mph in as little as 1.1 seconds. In a 2021 Joe Rogan interview he went further, stating “I want it to hover. We got to figure out how to make it hover without killing people.” Tesla filed a patent for ground effect technology in August 2025, suggesting the hover concept has not been abandoned. The starting price remains $200,000, with the Founders Series requiring a $250,000 full deposit. Some reservation holders placed those deposits in 2017 and are approaching a full decade of waiting.

With production now targeted for 2027 or 2028 at the earliest, the Roadster remains Tesla’s most audacious promise and its longest-running delay. But if what Musk is testing lives up to even half of what he has described, the demo alone should be worth waiting for.

Tesla isn’t joking about building Optimus at an industrial scale: Here we go

Tesla’s Optimus factory in Texas targets 10 million robots yearly, with 5.2 million square feet under construction.

Published

Tesla’s Q1 2026 Update Letter, released today, confirms that first generation Optimus production lines are now well underway at its Fremont, California factory, with a pilot line targeting one million robots per year to start. Of bigger note is a shared aerial image of a large piece of land adjacent to Gigafactory Texas, that Tesla has prominently labeled “Optimus factory site preparation.”

Permit documents show Tesla is seeking to add over 5.2 million square feet of new building space to the Giga Texas North Campus by the end of 2026, at an estimated construction investment of $5 billion to $10 billion. The longer term production target for that facility is 10 million Optimus units per year. Giga Texas already sits on 2,500 acres with over 10 million square feet of existing factory floor, and the North Campus expansion is being built to support multiple projects, including the dedicated Optimus factory, the Terafab chip fabrication facility (a joint Tesla/SpaceX/xAI venture), a Cybercab test track, road infrastructure, and supporting facilities.

Texas makes strategic sense beyond the existing infrastructure. The state’s tax structure, lower labor costs relative to California, and the proximity to Tesla’s AI training cluster Cortex 1 and 2, both located at Giga Texas and now totaling over 230,000 H100 equivalent GPUs, means the Optimus software stack and the factory producing the hardware will share the same campus. Tesla’s Q1 report also confirmed completion of the AI5 chip tape out in April, the inference processor designed specifically to power Optimus units in the field.

As Teslarati reported, the Texas facility is intended to house Optimus V4 production at full scale. Musk told the World Economic Forum in January that Tesla plans to sell Optimus to the public by end of 2027 at a price between $20,000 and $30,000, stating, “I think everyone on earth is going to have one and want one.” He has previously pegged long term demand for general purpose humanoid robots at over 20 billion units globally, citing both consumer and industrial use cases.
