Then we should all do that. Did you know all battery manufacturers recommend storing batteries at room temperature? What does that have to do with anything?
Manufacturers make recommendations based on their own best interests. If you try to pin them down, they will always recommend what's best for themselves, without regard to their clientelle.
Batteries last almost interminably in a freezer, and go bad soonest the warmer the environment! But they must know what's best for everyone! And companies are nice? They don't want to trick people into believing one thing and not the other.
Granted, there's a lot more at stake with an auto in a front pocket! But the whole idea of proving a point, because 'it's what the manufacturer says', is flawed!
Is it really the 'best' way to change a faucet washer to put on work gloves, eye protection, steel-toe boots, an acid-gas filtering respirator, and even after all that, to 'use extra caution to avoid personal injury and/or death?'
No, it's not! Then why does the manufacturer recommend it? Because one time a guy left the water on and disassembled a faucet valve! But the drain was also plugged up, so there was sitting water on the basin. When the faucet valve was taken apart to replace the washer, the water pressure caused it to burst open, which caused the sitting water full of acidic drain cleaner to go in the guy's eyes, and in his mouth, so he breathed it in, and went blind and got permanenly lung damage from it!
So, the faucet-washer company said, "We better warn everyone, so this doesn't happen again!" Plus, the guy was awarded 160 million dollars in a lawsuit. So, they put their heads together and came up with a list of precautions suitable to the task.
So, saying 'the manufacturer says so' is not evidence by itself that it is reasonable or correct. But I do happen to agree with you, anyway. I don't carry autos inside my pocket!
