People who purchase cars with individual climate control should just stay single. I mean, if you cannot even agree on what temperature to maintain your car cabin at, your marriage is already doomed. How the heck are you gonna decide on anything, ever? When you adopt a pet, are you gonna get a vertically split half pitbull half chihuahua? Teach your kid to play piano with one hand and strum the guitar with another? And what about those romantic moments? If you're drinking out of the same glass with two straws, will one of you insist on drinking coke from your side of the glass and the other a milkshake?
Does this thing even work? When hot air mixes with cold air, it turns into lukewarm air. Trying to have hot air and cold air in a single confined micro space is physically impossible. As impossible as having hot water and cold water in the same bathtub.
It is simple, really. You're the husband, you lose the fucking jacket because you get hot easily. You're the wife, you put on a fucking jacket because you get cold easily. That is what marriage is about, people, it is about compromise. Maybe if you followed this advice, it would save you a shitload of money on alimony payments. And save some for your mortgage payments. Perhaps bring the economy out of the shitter so that the rest of us can live our lives in peace.
