BS.Nope, all incidents are preventable.
Icy roads, don't drive.
Heart attack, get a medical.
Seizure get a medical.
Snow storm don't drive.
Every incident is preventable, peel back the layers on an onion sooner or later you'll find a cause or contributing factor.
But don't make uneducated or unknown assumptions to sensationalize the circumstances until you are informed.
Jumping to conclusions or uneducated assumptions is a pot stir'er.
