This was a good watch on why one must not sit idling your car to warm it up. What I do is I usually wait around 30 seconds after startup and then drive lightly until the blue cold temp guage in my car goes off.
This topic has been covered ad nauseum here but yeah, no need to idle the car for 10 minutes. When it's really cold out, I give my older cars about 2 minutes. Enough time to adjust the climate control, sip my coffee and get my tunes ready.

Old depends on how cold it gets where you live. For example, when the temperature drops -20 or colder there is no way you can safely drive your car 2 minutes later. How would you like -20 degree air being blown on your face?
On my side of the pond remote starters are most common, and these are set for 15 to 25 minute runs.
I've experimented with this as I did live one Winter entirely in my FI minivan. What you have to do for a quick warmup of the coolant is rev the engine higher after starting [wait 10 to 15 seconds, I rev it about 2000 to 2700 rpm]. More combustion = faster heatup, because modern ecu FI controlled engines do not rev higher upon startup.
forget about that new news. I am warming my car up for at least 5 minutes, winter or summer. I want everything up to tempeture. I aint playing with over 200000 miles on the car. when it idles at 750 rpm, like it supposed to do, I drive off.
Don't know about other cars, but my Corvette , after running for twenty or thirty seconds after starting, shows "brake before shifting", on the information screen, which means that is the time to start driving the vehicle.

Yes they do. At least all the ones I have seen do. Not 2000 RPM, but still higher than normal idle speed for a few minutes.

Modern cars do have a higher idle when the engine is cold.
And how is this different than driving the car lightly? If you wait 30 seconds then drive the car lightly, you'll warm up the engine and all the other components at the same time.
Isn't part of the reason you warm up for a short time so that the oil can circulate?
I live in extreme cold, and I wouldn't think of just starting my car and quickly driving off.
