I was curious about the result of the investigation since the article you linked said it was not yet known whether the self-driving features of the Tesla were active during the accident.

The outcome of the investigation was that the Autopilot was not engaged and the cause of this particular crash was human error:

"Per the investigation, the car data showed that the driver hit the gas pedal rather than the brake. The Model S then entered the rest stop, going 60 mph, hitting a curb and then the trailer."

And another source that's not a Tesla-focused website:

I'm not saying Tesla's self-driving tech is safe or trustworthy, but this is not a relevant example.

Someone can wish no ill to others, yet still find irony or absurdity in things that already happened. It's something that both victims and witnesses often do as a way of processing life's darker realities. Please don't tell other people how they should experience tragedy or speak on behalf of victims. You're no better situated to do that the person you responded to.
