Twitter's Revenues Are Now 40%

Twitter announced revenues are now 40%. I would be curious to know how that calculated that. Elon Musk tweeted the video at the time Tesla drives itself no human input at all. The director of autopilot software said the video was not intended to show what was available for customers but rather was possible to build into the system during the four month period in 2022 11 people were killed and crashes involving automated driving systems 10 of those involved Teslas.
