You should not need to warm up modern cars.
Just get in and drive it but dont take it over 3000rpm or so. Letting them warm up just results in the car taking longer to get up to temp and causes fuel to be wasted, and the engine actually produces more emissions sitting idling when warming up than it does getting driven.
The only advantage to warming up a car is the interior will be warmer when you get in. Modern cars are designed to be run from cold. They do not need warming up especially in moderate / warm climates. In below zero weather 30 seconds will do to warm them up.
And it can actually damage the injectors sitting idling. This is due to the car not effectively using the engine to burn fuel properly. So it results in deposits forming.
So basically let it warm up for 30 seconds then drive it but dont take it above 3000rpm. Will heat up much faster. Is kinder to the environment moving and is better for your engine.
Older cars different story, newer cars no need to warm up. Not sure why so many people bother about heating it up when half the videos I have seen they crank the car over from cold and then proceed to rev it numerous times. Something that is notoriously bad for your engine. Bit ironic really.

Let it warm ! Your main wear (colder temps) is on your piston rings.The colder the engine the tighter the clearances are.
Cold=contraction Hot=expansion,So by letting it warm (within a limited time)you get less engine wear.
The wear from friction at colder temps will be less at 700rpm(idle) than at 3,000rpm!
Of coarse theres more variables to this but I'm just stating some basics.(Oil temp to flow,Temps at start up,weight of oil...etc..)

99% of wear is at a cold start up with semi dry cylinder walls. Once the engine builds up oil pressure which is after a second or so of running, all that goes away.

Only in the winter time do I let mine idle for any length of time. Normally, Ill start the car, let it idle for about 10 seconds, then slowly drive away.

I let the RPMs come down below 700 before starting
out and dont ram and jam until I see the temp guage
come up. Then its bar the door, Katie.

i like to start mine up, then floor it a few times to blow out any carbon buildup. j/k

I drive mine so much it rarely has a chance to cool down
