I guess letting it warm or not doesn't matter. Just keep it on a low a bit for sometime.

I let my E90 warm up for about 2-5 minutes. A little bit longer because it's been hitting under 40 degrees Fahrenheit here in San Diego at night. (I know, so cold brrrrrrr)

I wait until the engine comes off high idle before driving, and keep the revs low for the first few miles.

I just start and drive about 20 sec. That about the time I put my phone on its mount and buckle my seatbelt. And then again 20 sec plenty of time to get the oil circulate.

On cold starts I suggest locking it in a higher gear and flooring it, helps warm up the turbos and engine faster.

Same here. Let the revs drop, takes maybe 30 seconds. I do that year round.

Then while going light on the throttle I usually shift under 2500 RPMs for a couple miles and then keep it under 3k RPMs until the engine reaches operating temp.

All I know is what I do wont hurt the car, but driving hard after cold start certainly could.

I don't warm it up really, but I do take my time to leave from my spot, e.g. look at the gauges, look around my surroundings, wait for garage door to close, check my rear view mirror, etc. before actually leaving. So with all this, this is pretty much my warm up time.

Warming up the car is a practice that is not current anymore with all fuel injection vehicles. In fact letting the car warm up in idle for the car means that the "normal" functional temperature will take longer to be reached, and the car will have to compensate that by injecting additional fuel into the combustion mixture and we can say that that is "not beneficial".

a few seconds or a minute or 2 is more than enough to make the oil engine moving, after that driving smoothly until it reaches the "normal" operating temperature is the best practice for the sake of the motor

No need to idle for minutes on end. You want oil pumped back to the top of the engine which occurs in the first few seconds of running, then take it easy on the gas until there's temp in the coolant AND in the oil.

the duration of warming up depends on the temperatures for me but i believe waiting a little is good for every engine.. in hot summer days a 50-60secs will be enough.. in really cold ukraine winter i do wait 2mins at least.. and in super cold winter days i never turn off the engine when its super hot.. like pushing it for a while before reaching the destination.. i believe its not good also.. driving calmly in last 3-4 mins before i arrive..

if more than 12 hours past i do wait at least rev goes down.. for my current ride i press M button and wait till exhaust flaps open on its own.. then i go.. driving progressively higher revs till oil reaches optimal levels..

below -10c things are not like that cause viscosity changes also.. thicker oil cant reach every part of the engine %100 for a while.. actually cold start behaviors is affecting a lot for engine's lifespan.. not even talking about turbos..

at -10*C yes you'd need 45 seconds or a minute to get enough oil moved around.

My garage drops to about 50* when its in the teens F* outside, so it has to get pretty darn cold to drop the temp in my garage to the mid 40s. That's only happened once or twice and both times it was below zero F outside

If you're car is constantly in temps that are well below freezing you may need to let it idle for a short period but no need for a 10 minute idle session.

It's called multi-viscosity oil for a reason...

Accelerate pretty gentily until oil temp is at normal then enjoy a few higher revs.

If the temps were crazy cold like in some places in the world? I’d probably give it more time before setting off, but “cold” here in Melbourne is like 10C (50F), so no need.
You have NFi what cold is. NONE, fuckign zero. Shuddup.
