Autonomous mobility
How capable will self-driving vehicles, drones, ships, and industrial machines become outside controlled settings?
Driving is the furthest-deployed case of open-world embodied autonomy, with quantified safety records now public — a preview of the deployment, liability, and trust questions every other mobile system will face. (Military autonomy is treated under Safety 2.5 and Power 4.3.)

What changed
01
Independent validation arrived: IIHS — not Waymo — finds 68% fewer police-reportable crashes than human drivers over 50 million driverless miles, while Waymo's own 170-million-mile update claims a serious-injury crash prevented every eight days. The number that changes the economics debate: roughly 70 remote overseers per 3,000 vehicles. Tesla's robotaxi data, by contrast, has to be reverse-engineered — and looks an order of magnitude behind.

Waymo's driverless cars crash less often than peopleThe results show that, on a limited scale, these driverless cars are safer than human drivers — who can be impaired or drowsy or suffer lapses in attention.
First fully independent validation of robotaxi safety claims: 68% lower police-reportable crash rates over 50 million driverless miles, with caveats on small samples in Austin and inadequate federal data collection.
Waymo · 19 Mar 2026 report
Waymo Safety Impact update: 170 million rider-only milesour analysis suggests the Waymo Driver is preventing approximately one serious-injury crash every 8 days.
Update to the canonical rider-only crash benchmark: 92% fewer serious-or-fatal-injury crashes than matched human drivers across 170M autonomous miles — the largest self-reported safety dataset in open-world autonomy.

Waymo just revealed a crucial statistic for scaling its technologythe vehicles have the ability to 'phone home' and get assistance from humans if they encounter situations they don't understand.
First hard number on the human-in-the-loop overhead of driverless scaling: roughly 70 remote overseers for a 3,000-vehicle fleet — the key economics-of-autonomy statistic the industry had never disclosed.

Does Tesla Really Have A Robotaxi? They Don't Make It Easy To Find OutOne has to ask why, if the data would suggest they are ready to go, they want to keep it hidden.
The most careful independent read of Tesla's robotaxi expansion: an estimated 15 crashes in ~800,000 supervised Austin miles, far behind Waymo, with deployment decisions tracking CEO optimism rather than disclosed performance.

Human drivers keep crashing into WaymosAnother way of looking at it would be, well, would a taxi stop here?
Crash-by-crash review of 78 serious Waymo incidents over seven months: 61% were rear-endings of Waymos, and only one involved a moving Waymo plausibly at fault — but lawful-yet-unnatural robot driving creates its own hazards.

House Cleaning My January 1, 2018 PredictionsThere have not been any plausible demos of this capability
Brooks retrospectively grades 8.5 years of self-driving predictions: driverless taxis remain limited to two operators, and his 'truly driverless' bar only survives by admitting remote human intervention — a disciplined base-rate check on deployment speed.

Zipline eyes Houston, Phoenix after 2 million drone deliveriesAutonomous logistics has become an everyday staple for people across several states in the US.
The drone side of open-world autonomy: 2 million commercial deliveries, 125 million autonomous miles, and 15% week-over-week US growth as delivery drones quietly scale.
