Federal auto safety regulators have granted a five-week extension for Tesla to respond to allegations that its vehicles have broken traffic laws while operating in what the electric automaker calls “full self-driving” mode.

Tesla's Full Self-Driving (Supervised) may not actually be autonomous, but it is still one-of-a-kind in the U.S. even years after its initial launch. For now.

Tesla's 10-billion-mile autonomy requirement builds an uncrossable data moat—use weakness below $400 to accumulate.

The purpose-built robotaxi prototypes have been seen on busy South Austin streets since late December but nighttime highway travel is more complex.

Absent a federal standard, states that allow autonomous vehicles, or AVs, to circulate have had to make up their own rules. But is that safe enough?

Mercedes-Benz will launch a new advanced driver-assistance system in the US later this year that lets its vehicles operate autonomously on city streets under driver supervision.

The Elon Musk-led automaker asked highway safety regulators for more time to manually review thousands of records to identify incidents that may be relevant.
