Tesla’s Full Self-Driving (FSD) mode is an impressive feat of technological engineering, able to complete a vast array of human-like maneuvers and responses. The perhaps misleadingly named, partially automated driving system is far from infallible though, as recent tests show.

AMCI Testing put FSD through its paces in four different environments in Southern California: city streets, interstate highways, mountain roads and rural two-lane highways. And while the system did demonstrate some sophisticated driving capabilities, it also needed human intervention/correction more than 75 times throughout the more than 1,000 miles driven.

That’s an average of one intervention every 13 miles. “It’s undeniable that FSD 12.5.1 is impressive, for the vast array of human-like responses it does achieve, especially for a camera-based system,” said AMCI Testing Director Guy Mangiamele. However, “the most critical moments of FSD miscalculation are split-second events that even professional drivers, operating with a test mindset, must focus on catching.”
