But driving? It’s like their strength fell off a cliff.

Getting fatigued usually doesn’t get quite this severe. No one believed it would get so bad that they couldn’t move anymore, that’s hardly normal. Now, a reasonable person would say they shouldn’t have been driving anyway, but no one was there to provide them with the necessities after all of society’s basic functions just totally collapsed.
