Musk did say "unsupervised" FSD would be capable of driving with "no one in the car."
Such comments often leave investors guessing what Tesla will actually deliver, and when, said Brian Mulberry, client portfolio manager at Zacks Investment Management, a Tesla investor.
"This is the challenge with Elon: You're kind of reading through the tea leaves here and trying to extrapolate from some fragments what might actually happen," he said.
Mulberry added he was not particularly concerned about the specifics of Musk's promises and timelines this year, provided Tesla shows progress: "The blueprint, I think, is there."
