#1 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 #2 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.#3 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.

I let my car warm up for the length of time it takes for the garage door to come down. Then I let it idle around the U-shaped street we live on, about an eighth of a mile, by which time the idle drops and I go away. There is almost no reason to go ove 3000 rpm in any gear on surface streets. By the time I'm ready to merge onto a freeway, I am ready to merge at whatever speed is required.
Once the lubricant is circulated - 15 to 20 seconds in modern cars - there is no reason to sit still, and plenty of reason to start moving: the engine will warm faster, which has multiple benefits. Before modern fuel management, at "low" engine temperatures and speeds, there was excess fuel drawn into the combustion chambers, and while most of it came out the exhaust, too much flowed past the rings and into the crankcase. Cold cylinder wall become warm more quickly when the car is being driven.
I believe this is not as much of a hazard as it was, but it still accounts for some of the contamination you can see in your oil when you drain it for a change.
All those smog sensors will do what they are expected to do, and with gentle throttle application for the first minute or two of driving, so will the lubrication and fuel systems.
Start it, sing "Happy Birthday to you ... " twice, and drive easy.

And in regards to number 1...it is true modern cars do not need to sit idling on your drive for 10 minutes before you drive them. Its just a waste of gas. Which works out at several hundred $'s a year. It only takes a few seconds for the oil to circulate and then the car can be driven. As I also said best to keep it under 3000rpm while the engine warms up properly before gunning it.
Stop being such a smart ****. Go and read about modern oils and engines. And you will hear the same thing....Modern cars do no need to be heated up like older cars. Oils have a lower viscosity now then they used to when cold. Which helps them circulate better at start up hence you dont have to wait on them heating up before they start protecting properly.

RE: Warming up the engine???
I don't agree with wozz's assessments. Modern cars have EFI to mask the fact that older cars with carbs had to warm up so they wouldn't stall(remember manual chokes?), newer cars don't stall, but they will hiccup(mine does if I don't allow it sufficient time to properly warm up).
I realize old habits die hard, but my 1st ex wife just had to recently buy a new car because she grenaded the engine in her 2000 VW GTI(I bought a new Frontier Crew Cab around the same time, we were still married at the time) and she only had 125K miles(when I sold my Frontier in 2005 to get my first S197 GT, I had 115K mile and it ran like brand new, still does, I know the guy I sold it to).
I know her like the back of my hand, she gets in ,starts it up and takes off. No warm up, I told her to at least take it easy, she tried, but, well I won't get into that
. Warm up is essential IMO, at least a few minutes(for me it's peace of mind and I've never blown an engine in any of my cars/trucks). Change your fluids, belts and let your engine properly warm up. JMHO
