I think TSLA investors may be a little sensitive about anything "fire" related since they've been burned by the 2013 incidents, hence the initial reaction on here to this latest news. But recall, on Oct 1, 2013 when the first road fire was reported, after an initial selloff from the all time high of 193 at the time, it recovered to 189 two weeks later. In other words, the market shrugged it off after the initial reaction. The much larger declines that followed only ensued after multiple fires reoccurred, which ignited fears that it was a widespread problem which represents existential risk to the company.
To equate what happened then(after multiple fires) to this 1 in a million charging fire which may or may not even be a result of charging or anything Tesla related is a mistake.
In that light, I am actually quite disappointed that the markets are not open today, as a reactionary buying opportunity may have been missed.
