Saddening.
Happened to a friend of mine last Oct. Age?: About 65+. He just "lost it" on a flat, straight road, for
no identifiable or at least plausible reason whatsoever.
He was much later (
after all his injuries, some near fatal, had been looked after) found to have a so-called "heart condition". Condition that had
never manifested itself before the accident... but which had momentarily caused his heart and thus his brain to switch off.
