It's like lithium ion batteries. There is a set of "rules" for taking the best possible care of the battery, but you mostly can't actually follow them, while still getting any utility out of them since adhering to them strictly is almost more effort than living without a battery.
So all that's reasonable is simply to be aware of the ideals, and by inference the anti-ideals, and let them guide whatever freedom you do have, while just using the thing however you need to.
If you need to actually use your laptop on batteries freque tly, then go ahead and allow it to charge to 100% instead of limiting it to 50% to 80%. If you live somewhere cold and need to use a device in the cold, well then you just go ahead and use it outside of the ideal temperature range.
But the knowledge is still useful because there are still plenty of times where you could do any number of things and don't much care which since they're all equal effort, but they aren't all equally good for your equipment, and all else being equal, you would be just as happy to adopt a habit that gives x extra years of lufe than one that removes x years of life, if you simply knew about it.
Like, you don't really care that much where in your house you plop some device when you're not using it for weeks at a time, but a shelf in a covered cabinet is better than a table in direct sunlight, is better than sitting directly on top of a steam radiator.
Your work commute precludes the absolute ideal, but within your limits there is still a lot of opportunity to do things more vs less optimally. You might intentionally take local roads to the next exit, or for merely 10 miles even the whole way.
Or just don't even worry about it at all because diffs and trannies are really not what die first or most, and trannies do warm up some just from the torque converter pumping and the radiator loop.
And manuals just aren't a problem no matter what. They may shift harder but they aren't being hurt much. In any climate that even has cold, everything else will rust to junk before a manual tranny even needs a new clutch let alone any kind of actual wear to the gears or synchros.
