I Tested Tesla’s New Full Self-Driving Software. What I Thought After More Than 1,000 Miles.

Barron’s, via me, has tested Tesla’s FSD driver assistance features several times for many months. The reason for a primarily stock-focused publication testing cars should be obvious: Developing and improving self-driving cars is a big deal for the industry and for Tesla stock. In the first test circa 2023, I said FSD drove like a mash of a teenager with a learner’s permit and an octogenarian—like my Dad who prefers caution no matter how everyone else is driving around him.
