There is a certain personality type common among midwits who are smart enough to think of the most obvious workaround/solution/exception but not smart enough to realize that when people communicate, especially online, they usually choose brevity over exactness.
Like if I say "Humans have two feet" some midwit will come along with an article or anecdote about a person who was born without two feet.
And if I say the multi-hour outage of AWS made my friend minutes late because of her car warmer, what is going through the mind of a person who offers the solution "Did she try walking to the car and turning it on manually?" These are the kinds of people that if you met them in real life you'd quickly distance yourself from them.

It's autism.
One of the symptoms of autism is [the inability to recognize sarcasm](http://www.healthcentral.com/autism/c/1443/162610/autism-sar...) without the help of idiotic, illiterate signals like "/s". Your example has the same cause; people who are unable to understand nuance and social cues, whether in real life or in written form.
"Yes, the dumb broad didn't think to walk outside and turn the car on! I shall right this wrong with my clever internet post! Behold my intelligence!"
