According to this interview, when asked to describe his immediate reaction to learning of the Cybertruck crash, the victim’s father said he was confused due to Tesla app failure:

Usually I wake up at 4:30 and I go through the Tesla app to see if he’s heading home or at the gym. His car is at the gym, so I continue my workout and my daughter said, ‘What are you doing?’ I said, ‘I’m working out.’ She said, ‘You haven’t heard? Your son just got in an accident.’ ‘At the gym?’ ‘No he’s at the hospital.’

I just stopped everything and ran over there and was like, ‘What the hell’s going on? Was it his car? What’s going on?’ I realized the app actually malfunctioned. I found that out a couple days later when he started waking up.

His son was released from the hospital last week, after being placed in a coma due to smoke inhaled while trapped inside the Cybertruck for at least 10 minutes.
