Re: windscreen wipers?
"still doesn't have anyone to look out the wiped windscreen. So why leave the rain sensors hooked up to the wipers?"
Surely Glen Waverley was being sarcastic when he wrote this, no?* Was his point not, by posing the rhetorical question, to induce everyone to reflect and realize the obvious ridiculousness and unnecessary complication of the alternative — namely, of connecting the passenger-presence sensors to the interface between the vehicle's rain sensors and its windshield-wiper motors, and making the "On" or "Off" status of the latter interface or connection depend on the presence or absence of passengers?
I believe that the several responses his comment received were actually just repeating his point.
(Apropos of which, remember that part of the point of the "Joke Alert" icon and the flashing "Joke Alert" gif is to poke fun at those who make their use necessary. If memory serves, the introduction of the flashing "Joke Alert" gif some 10-14 years ago was accompanied by words from Lester to the effect that "We wouldn't have thought additional words were necessary to make clear that we were joking" — about what, I've long since forgotten — "but obviously we were wrong.")
* I don't believe he was being sarcastic or insincere in his original post. I believe that post was merely intended to point out the irony of having the windshield wipers on even when no one is in the car. But I honestly do believe his latter post, or at least its second paragraph/final sentence, were intended to be sarcastic. I looked for any follow-up posts in which he might have defended his later assertion, and was relieved to find none.
But obviously I'm kind-of out on a limb here.
