Zoox grounds its Atlanta fleet after drivers got sick in the cars
Amazon's robotaxi unit has halted testing in Atlanta while it works out what made its safety drivers sick inside the vehicles — and Intel spent its China conference shipping hardware for robots instead of talking about the CPU squeeze underneath them.
Zoox has grounded its autonomous test fleet in Atlanta after safety drivers were potentially exposed to carbon monoxide, carbon dioxide or hydrogen sulfide inside the cars last month, according to a TechCrunch investigation published Wednesday. An OSHA letter seen by the outlet puts possible exposure at as many as 40 workers; Zoox says the number is lower, and told the agency it identified 28 employees who rode in six vehicles with an "unexplained odor," ten of whom voluntarily underwent medical evaluation. Only one medical report identified CO2 exposure. Three workers went to an emergency room after an August 14 run in which a colleague vomited at a Chick-fil-A stop, and contractor Jay Davis — who filed the OSHA complaint — says the crew was sent back out in a different test car that same day. "They made us go right back in the field after we said we were throwing up," Davis told TechCrunch.
The depot in northwest Atlanta has operated at limited capacity since August 22, when someone called 911 for a sick worker, with the vehicles quarantined. OSHA opened an inquiry, told Zoox to investigate, and has since closed it; Zoox says it tested exhaust systems, replaced the 12-volt batteries, found only CO2, and will fit the cars with CO2 monitors. Its purpose-built electric robotaxis are not affected — the grounded fleet is modified Toyota Highlander SUVs with internal combustion engines, which makes Zoox the outlier among major robotaxi developers. The uncomfortable part is the pattern, not the gas: the same company was already the subject of an August investigation into test drivers hurt by hard braking, and the fix here was monitors and a battery swap while the people in the cars kept being treated as sensors. We covered the wider problem in August — Waymo and Zoox test drivers are getting hurt as robotaxis scale. No second outlet has independently confirmed the Atlanta halt, so treat the exposure counts as Zoox's and OSHA's versions of the same week.
Intel used its annual China ecosystem conference in Suzhou to launch an embodied-AI development kit that it says cuts average real-time control jitter to 1.6 microseconds, aimed at getting robot projects from prototype to production. The kit, built with Comtech Industrial and Digital China on the third-generation Core Ultra processor, bundles the hardware and software for a full perceive–plan–execute loop that developers can run out of the box — a small number on a spec sheet, but jitter is the metric that decides whether a robot arm can be trusted near a human. Intel also said the third-generation Core Ultra line has passed 400 customer designs and previewed an 18A-P process node for 2027 claiming 9% better performance per watt and 18% lower power at the same performance, alongside new Arc Pro B70/B65 professional GPUs. The strategic read is a company that lost the training-compute story trying to own the inference-on-devices story, from agentic PCs to hotel and hospital agent boxes to robots.
Worth holding both halves of Intel's week together: CEO Lip-Bu Tan said this month that agentic AI has pushed CPU demand past what Intel can supply, meeting roughly half of what customers want, with customers calling him directly to expedite orders — a shortage that CTech and Motley Fool both reported. A robotics dev kit is a bet that the CPU, not the GPU, is where the next wave of AI spending lands.
What to watch: whether Zoox returns to Atlanta streets or quietly drops the market, and whether the CO2 monitors come with an actual ventilation redesign on the gas-powered test fleet.
Should robotaxi companies be required to report test-driver injuries the way they report crashes — or is a regulator closing the file the end of the story? Tell us in the comments.
