More like seatbelt is muscle memory they don’t actively think about. Nobody is mentioning closing the door or aligning their foot to the pedals either.
You are absolutely not supposed to do that. In fact, you’re supposed to do the opposite. Letting your car idle to warm up kills it faster because the oil pump isn’t running because the car isn’t moving.
The exception to this is:
A) when it’s really freezing cold out, and then still not more than a minute (not “at least a minute”. No more than a minute. 30 seconds is plenty in winter. To be clear, if it isn’t cold out, this doesn’t apply, and you shouldn’t wait at all.
B) if your car is ancient, like with a manual choke or similar. Well over 40 years old.
This is 100% correct. There’s a lot of “tips and tricks” that are extremely out dated, and typically for vehicles prior to the implentation of fuel injection.
The oil pump is running but it is generating less pressure at idle.
You should however keep the revs lower, not as low as idle as you point out but also don’t red line it. If it’s a turbo try not to generate lots of boost either.
Oh so if the manufacturer says so? So it’s not in fact a myth or lie? With three exceptions.
One thing I have found really annoying about Lemmy is there are tons of trolls just here to be contrarians. I’m here for debate and to learn. But so many people are just assholes, miserable in their life and looking to bring down everyone else. Unnecessarily rude.
to be fair, the last point more so covers margin cases that are more likely to be covered if the user/driver informs themselves than trying to list every margin case here.

That is absolutely not true. The engine runs the oil pump, so the pump is working as long as the engine is spinning, assuming the pump is not faulty, of course. I’m not aware of any car engine ever built where that isn’t true.
That being said, idling your (modern) car for longer than a minute, or as long as necessary to defrost the windows in the winter, is a waste of fuel and, consequently, emissions. It’s also an unnecessary wear on mechanical parts, but not because the engine is cold or hot, but simply because it’s in use.
The car doesn’t have to be in gear for the oil pump to run. If the engine is running the oil pump is on. That’s why there’s a red light that looks like an oil can when the key is on before you start it but it turns off when the engine is running because there is oil pressure. If that light is on when the engine is running you need to shut it off immediately or you’re going to be replacing an engine.
Waiting for Bluetooth to connect, putting on seatbelt, fixing Bluetooth, putting drinks in drink holders, waiting for Bluetooth, turning on lights, fixing Bluetooth.
Letting the oil circulate before putting load on the engine. Only needs an extra 10-15 seconds, or the time it takes me to scrape during the winter months. No time needed if it was recently running.
Oil pumps? Seriously though 10-15 seconds doesn’t sound excessive at all. I would be surprised if anyone is actually in gear and putting serious load on their engine/trans in under 10 seconds.
Like that ever stops anyone. Georgia is a hands-free state (not really because people eat, do makeup, and whatever else), but I always see people on their phones while they drive.
Perhaps it’s more of a “hey, parking is hard to come by in this neighborhood… I’ve been circling for a while and noticed that you got into your car and now I’m sitting here with my blinker on, blocking traffic, waiting for the spot to free up so I can park and get on with my day… what’s going on in there?”
You’re the asshole in that situation. Don’t expect that any parking place is yours until it’s empty, especially when you have no idea when the people actually parked in the space are leaving. You should never be blocking traffic waiting to park in an occupied space because you assume they’re leaving.
I understand this. At work parking is hella bad, so I routinely get to work over an hour early just for parking, and then most days I bring lunch or don’t eat because I don’t want to lose my parking during the day.
That being said, because I know parking sucks there, I’m extra quick when I do have to leave because I know the feeling of driving around looking for parking, becoming hopeless, and resigning to the quarter mile walk from the next closest available parking.
I’ve never understood the people who purposefully just sit there and stare at the person needing a parking spot in their rear view mirror waiting for them to leave. My dad does this, and I’m always just like “Aren’t you taking more time away from yourself now too just to stick it to someone else?”
Well I get in, plug in my phone and put on my belt. That’s maybe 15 seconds. Then I turn the key and wait for the glow* plugs to warm up, so that’s another 5-10 seconds.
