Facebook CTO shares insights on Tesla’s shift to pure vision for Autopilot
Tesla’s decision to abandon radar and focus instead on a pure vision strategy in its efforts to achieve self-driving features may be controversial even among the company’s most ardent fans, but Facebook CTO Mike Schroepfer seems to be on the EV maker’s side. In a series of posts on Twitter, the Facebook CTO shared his thoughts on Tesla’s bold strategy and why it may actually work.
Schroepfer, who is known for his work on artificial technology for Facebook, noted that Tesla’s pure vision approach is actually pretty clever. This is because Tesla has the ability to capture and label data at a fleet-wide scale. He also reiterated a point that Elon Musk previously made on Twitter—that sensor fusion becomes tricky, especially when two sensors disagree.
Given Tesla's ability to capture and label data at fleet-wide scale this is a smart approach. Computer Vision continues to advance quickly and we have a proof point in that human drivers don't need radar :).

Granted, radar has played a key role in improving the safety of Tesla’s vehicles. Numerous Tesla owners over the years have remarked that their vehicles’ radar has detected hazards on the road in situations where pure vision would have been compromised. It would now be up to the company to prove that its vehicles could maintain their safety even after losing radar; or better yet, improve their safety after losing the sensor.
Ultimately, Schroepfer also highlighted that humans drive vehicles with mostly vision alone. And while it is true that a well-rested, focused, and trained human driver would be excellent on the road, very rarely do drivers tick all three boxes at all times. This is proven by the fact that a good number of accidents on the road could be attributed to distracted driving or exhausted drivers. Computers, such as those used by Tesla, have the potential to tick all three boxes all the time.
Cost is what makes the difference between mass scale and not. External tracking using lasers gives you "actual distance" for Virtual Reality – but it wasn't until we shipped a $299 inside-out tracked VR headset "only" based on CV that VR is becoming real. Scale matters

In previous comments, Elon Musk has noted that a move to pure vision should help Tesla’s Autopilot and Full Self-Driving system improve significantly. The CEO hinted at some of the issues that such a change could address, such as phantom braking. However, Tesla is still maintaining its cautious stance amidst its shift, as evidenced by the company’s restrictions on features such as Autosteer when the pure vision update rolls out.
As per the EV maker, for a short period during the transition to pure vision, vehicles with no radar would have some features temporarily limited or inactive. These include Autosteer, which would be limited to 75 mph and a longer minimum following distance. Smart Summon and Emergency Lane Departure Avoidance may be disabled at delivery as well. These features would then be restored as over-the-air updates are deployed.

Elon Musk handed Grok something no other AI company can get their hands on
Elon Musk says SpaceX will feed engineering data into Grok’s next model, avoiding restricted material.
Elon Musk said Tuesday that SpaceX will feed its internal engineering data into the next major training run for Grok, the AI model now folded into SpaceX following February’s merger. In a post on X, Musk wrote that SpaceX’s “massive corpus of world-class engineering data,” excluding anything restricted under U.S. arms export law, will be added during supplemental training of what he called the “2T run,” a reference to a roughly two trillion parameter model that would nearly double the parameters behind the latest Grok 4.5 that’s rolling out.
SpaceX’s massive corpus of world-class engineering data (excluding material blocked by ITAR) will be added during supplemental training of the 2T run.
This will dramatically improve Grok’s engineering capabilities. https://t.co/BbQEViFByn

The excluded material that Musk is referring to would fall under the International Traffic in Arms Regulations (ITAR), which restricts export of technical data tied to defense and space hardware. That likely rules out propulsion specifics for Merlin and Raptor engines along with guidance and control details for SpaceX’s launch vehicles, but leaves manufacturing knowledge, materials science, and Starlink hardware design on the table.
The announcement extends a pattern that has been building since SpaceX’s Nasdaq debut in June, when the company went public with Grok and xAI’s Colossus supercomputer folded into the pitch to investors.
Days after that listing, SpaceX closed its $60 billion all stock acquisition of coding startup Cursor, giving xAI both enterprise software distribution and a stream of real world developer data to train on. Grok 4.5 launched July 8 running partly on that Cursor training data, with Musk describing it as roughly comparable to Anthropic’s Opus 4.7 but faster and cheaper to run.
Feeding SpaceX’s own engineering data into the next AI model follows the same logic Musk has applied across xAI’s sister companies. Tesla supplies real world driving data and manufacturing expertise, X supplies conversational data, and now SpaceX supplies aerospace engineering data built up since 2002.
Musk did not give a release date for the upcoming AI model, referred to elsewhere as Grok 4.6. He has said the two trillion parameter run is in its final training phase and expected to wrap this week.
Tesla has extended its Bay Area ride-hailing service to include pickups and drop-offs at San Francisco International Airport (SFO). The update, shared via the company’s official channels on July 21, allows users in the region to request rides directly to and from one of California’s busiest airports.
The expansion builds on Tesla’s secured limousine permit for SFO operations. Public records show the permit became effective March 20, 2026, and remains active through January 31, 2027. Tesla vehicles operating the service now display authorized limousine permits issued by the City and County of San Francisco.
Our Bay Area rideshare service now goes to SFO ✈️

Tesla’s ride-hailing program in California relies on Model Y vehicles equipped with Full Self-Driving (Supervised) technology. Human safety drivers remain present in compliance with state regulations, distinguishing the service from fully driverless operations.
The Bay Area geofence covers a broad area spanning north of San Francisco to south of San Jose, offering extensive connectivity across the region.
UPDATE: Elon Musk reveals why Tesla didn’t say ‘Robotaxi’ upon California launch
This SFO addition follows earlier progress at other Bay Area airports. Tesla previously expanded service to San Jose Mineta International Airport (SJC) in late 2025. The company had engaged with SFO, SJC, and Oakland International Airport officials as early as September 2025 to secure necessary approvals for passenger transport.
The service provides a new option for travelers seeking electric, app-based transportation integrated with Tesla’s ecosystem. Rides are booked through Tesla’s dedicated ride-hailing application, which handles matching, routing, and payments. Pricing follows standard ride-hailing models, with potential adjustments based on distance, time, and demand.
Tesla’s California ride-hailing program launched in July 2025 with an initial invite-only rollout in the Bay Area. It started alongside operations in Austin, Texas, marking the company’s second major U.S. market.
The Bay Area remains a primary focus in California, with service centered on high-demand corridors connecting residential, commercial, and now major transportation hubs. This latest airport integration represents a practical step in Tesla’s broader mobility ambitions within the state.
