Absolutely not. You can safely drive as soon as oil pressure builds to normal, maybe 15 seconds. Not only is an extended warm up unnecessary, it wastes gas. Just don't get crazy on the gas until it's you've been driving a while.

Warming up a car is really only important when it is very cold out. Even light weight oil with become pretty thick in extremely cold temperatures and thick oil doesn't flow as well or lubricate as effectively. If you start driving your car before the oil has warmed up it can cause unnecessary wear on your engine.
It doesn't take too long to warm up though - anything more than 1-2 minutes is just a waste of gas.

As a matter of fact, warming up your car is NOT a good idea when you are starting your car--and if you look at your owner's manual, I am sure you will see that same advice there. In the old days, you MIGHT have had to warm it so that the "choke" which regulated air/gas mixture would get "unstuck," but today's cars (after 1995) ALL have automatic chokes--if they have them at all--and you are just wasting gas and hurting your engine by that warming up. JUst drive it at a reasonable speed for 5 minutes and you will be better off!

Its not really that important at all any more.
If you start the engine as soon as you get in, by the time you get settled in, put your seat belt on, the airbag light goes out, etc the oil pressure will be up to specs and you'll be ready to go. Any increase in efficiency warming up the engine is cancelled by the fuel wasted idling. If you don't like a cold car, it is better to get heated seats than to let the car idle needlessly.

You really don't need much warm-up with a newer car. Thirty seconds in cold weather is sufficient, in most cases. Just long enough to get the oil circulating, to prevent excessive wear.

Just to get the oil circulating in the engine so its properly lubricated before you put the hammer down.
Also, in cold weather some warming can help prevent rubber parts from cracking. Old rubber especially can crack in cold weather causing leaks.

inside the engine is what is call;"the combustion chamber" and it get to 250 degrees just in the first second of cranking.
and that heat start spreading through the whole engine.
imagine....You get a block of ice from the freezer and suddenly in the center of it ,You throw hot-boiling water.What would happen?
same thing ,could happen to Your engine block,if You overheat Your engine combustion chamber suddenly.

Because your car needs to get rid of the bubbles in the oil so it doesn't create sludge in your engine, if you don't you gain the risk of slowing down your car ruining your piston rings and warping the engine, you need to bring it up to operating temperature...
