A Bay Area lunch run made national news when three engineers linked a general-purpose chat model to a 2024 Toyota Corolla, steered through an In-N-Out drive-thru, and posted the results. The stunt is easy to confuse with the robotaxis rolling through Detroit or the driver-assist software federal regulators are scrutinizing on millions of Teslas. It is none of those things. Understanding the gap matters if you share California surface streets with modified test rigs or if you are shopping for a Corolla and wonder whether your sedan will someday answer to a chatbot.
What actually happened on the drive-thru line
According to WIRED’s reporting, Aditya Ramabadran, Simon Mahns, and Tobias Gessler—AI engineers who work at a startup called Axiom—ran the experiment on their own time. They parked near an In-N-Out in the San Francisco Bay Area, opened a laptop, and piped camera feeds plus steering commands through a server into the Corolla’s power steering. OpenAI’s GPT-6 Astra, a model built for text and images, received the scene and issued low-speed steering requests. A human sat in the driver’s seat with a foot ready over the brake.
The car crept forward, lined up, and reached the pickup window slowly enough to collect food. The team also tried SpaceXAI’s Grok and Anthropic’s Claude Fable 5.1. Early attempts failed when models refused to send motion commands; only careful prompting unlocked movement. Separately, the group published a parking-lot benchmark called DrivingBench: Astra completed a simple course at crawl speed, Claude Fable 5.1 covered about 45 percent, and Grok about 11 percent. No public-road speeds, no passengers for hire, no manufacturer blessing.
Why this is not Waymo, and not Tesla FSD (Supervised)
Waymo’s Detroit rollout this week involves vehicles engineered from the ground up for automated driving, geofenced maps, and oversight under state permitting frameworks. Tesla’s Full Self-Driving (Supervised) ships on customer cars but still requires an attentive human who can brake or steer; the National Highway Traffic Safety Administration opened Preliminary Evaluation PE25012 in October 2025 after reports of red-light violations and wrong-way moves while the system was engaged.
The Corolla experiment sits outside both lanes. It used aftermarket wiring into steering, a laptop bridge, and a chat model that was not trained as an automotive ECU. NHTSA’s consumer guidance on automated features still boils down to one rule for anything short of a certified automated driving system: the licensed human in the driver’s seat remains responsible for safe operation and compliance with traffic law. Hooking a large language model to steering on a public drive-thru lane is research theater, not a feature you can enable in a menu.
What NHTSA and state law still expect from you
Federal safety investigations focus on production systems sold to the public. PE25012, for example, asks whether Tesla’s FSD detects signals and signs correctly and whether in-car warnings give drivers enough time to intervene. Recalls and investigations you can look up by VIN live on NHTSA’s recall lookup, the same database Toyota cites when it tells RAV4 Plug-in Hybrid owners to visit a dealer for a hybrid ECU software update.
California and other states additionally regulate testing of autonomous technology on public roads through permits and reporting. A one-off Corolla hack does not create a new compliance category for commuters; it reinforces that modifying steering or brakes without manufacturer approval can violate vehicle equipment rules and insurance terms. If you see a sedan crawling through a restaurant line with a laptop on the dash, treat it as an unverified test vehicle: increase following distance and avoid pacing alongside.
If you drive or buy a Toyota Corolla in 2026
Production 2024–2026 Corollas sold in the U.S. offer Toyota Safety Sense—lane keeping, adaptive cruise, and automatic emergency braking—not chatbot steering. Those aids still need your hands on the wheel and eyes on the road; they do not replace driver education or state DMV vision and renewal rules. When you evaluate a used Corolla, run the VIN through NHTSA’s recall page and Toyota’s recall portal before you sign, and cross-check open safety campaigns the same way you would for any other model year.
Before you pay for a private-party Corolla, a quick pass through CarDiary’s VIN check helps you capture open recalls and basic vehicle history in the same log where you track registration and service, instead of juggling another spreadsheet tab.
Where “physical AI” may go next—and what to ignore
Researchers at Scale AI and startups such as Elorian AI are publishing benchmarks that score how well models understand scenes, not just pixels. That work may eventually improve warehouse robots or in-cabin monitoring, but consumer vehicles will still pass through FMVSS crash standards, dealer networks, and NHTSA defect channels long before a chat interface controls your commute.
For now, the lesson from the In-N-Out Corolla is narrow: general-purpose models can sometimes translate camera input into rudimentary steering in a controlled creep, yet they fail most structured driving tests and they lack the redundancy, validation, and legal packaging of production driver-assist or robotaxi stacks. Enjoy the headline, keep your foot near the brake on your own car, and leave the chatbot experiments to fenced parking lots.
