Elon Musk Promised "Over a Million Robotaxis" by 2020. Six Years Later, Tesla Has a Handful of Modified Model Ys With Human Babysitters.

The man who once said timelines are merely "aspirational" really outdid himself here. Musk confidently declared that Tesla would have over a million robotaxis on the road by 2020 — they'd just "wake up" with a software update. Simple!

Reality had other plans. As of April 2026 — more than six years after the promised deadline — Tesla's robotaxi service consists of modified Model Y vehicles operating in a limited Austin, Texas pilot... with human safety monitors in the driver's seat. An Electrek analysis found the service had just 19% availability eight months after launch.

The goalposts haven't just moved; they've gone on a cross-country road trip. Musk recently admitted Tesla needs 10 billion miles of driving data for "safe unsupervised self-driving" — a threshold the fleet won't hit until July 2026 at the earliest. The dedicated Cybercab production? Maybe April 2026. Regulatory approval in Europe? Hopefully February 2026.

To be fair, Musk did include a failsafe in his original pitch: "regulatory approval is the big unknown." Turns out there were quite a few other unknowns too — like whether the technology actually worked.
