I haven't read that (paywalled) article, but I will note that she died on Feb 11th, while a Tesla recall was issued on Jan 26th for a software glitch that can prevent rearview cameras from displaying properly. It appears her death is under criminal investigation, so I presume they're investigating the possibility that the rearview camera glitch was intentionally exploited.
