Tesla's most fervent supporters are exhibiting some odd behavior on social media and in forums regarding the Texas crash in which, according to local police, no one was in the driver's seat when a Tesla crashed into a tree and two people died. Rather than waiting for the two different federal authorities investigating the crash to publish their findings, some Tesla owners are engaging in the classic behavior of conspiracy theorists and amateur internet sleuths in an apparent attempt to cast doubt on even the most basic facts surrounding the crash. 

The basic narrative is this: a Tesla vehicle crashed into a tree, exploded, and two people died. Local police officials said no one was in the driver's seat, and later confirmed they "are certain" no one was in the driver's seat at the time of the crash. Naturally, this resulted in speculation on social media and by many news outlets that one of Tesla's various driver assist features—which are confusingly named to imply they drive the car when in fact they do not and have been well-documented to be abused for years—was engaged at the time of the crash.
