It's not just P&P, but two examples that come to mind are the way the other ladies react as if Elizabeth were planning to swim the English Channel when she walks the three miles to Netherfield. I'm sure lower-class women of the era walked that distance and more on a regular basis.

Also, I'm torn about Jane's illness. On the one hand, I know full well that a cold turning into a more serious illness was always a possibility. (My own grandfather, a seemingly healthy man in his 30s, died of a cold that turned into pneumonia in the pre-antibiotic era.) Still, why does she need constant attendance, and only by a family member? Maybe I'm biased by my own feelings, but when I'm not feeling well, I'd like people to check on me every once in a while, but for the most part I just want to be left alone to sleep! (Of course, being in a strange house would make *some* difference...) Again, I'm sure that lower-class women didn't have the luxury of such constant care when *they* had a bad cold!
