On self-driving cars: "In medicine, when a treatment shows this level of benefit, we stop the trial early. Continuing to give patients the placebo becomes unethical. When an intervention works this clearly, you change what you do. In driving, we’re all the control group."

Why it worked

Opens with a short, self-contained line that is easy to take in at a glance.
Contradicts something the audience already believes, which stops the scroll.
Follows a clear Hook → Context → Landing shape, so the reader always knows where they are.
Ends on a short line that is easy to quote and repeat.
The opening line stands alone, so it reads completely before the post is expanded.
Written from experience rather than as advice, which is harder to argue with.

The mechanics

Hook: Plain observation
Structure: Hook → Context → Landing
Style: Conversational paragraphs at a steady pace.
Tone: punchy, corporate
Mechanisms: Pattern interrupt
Written for: Founders, marketers and operators
