Older or newer car are both the same...they are made with metal....use your kids school physic laws here...
For that said. The best thing to do is to let your car warm up to normal operating temp, then give it 1-2 minutes more.
The only thing that newer technology does to modern car is the oil system. It can deliver oil pretty quick to most parts of the engine when turn key, but the property of metal and temperature will never change

There is more contradictory information in this post then is real.
Oil varies in weight/viscosity so it can be used at different temperatures. So there is no need to wait for normal operating temperature before you start driving. Driving the car will allow the engine and oil to warm up more quickly than just letting it idle. The important part to remember is to allow the engine to come up to operating temperatures before pushing the engine or going WOT.
Letting the car sit there idling to warm is bad and will dilute the oil with fuel from the rich cold start mixture. It will warm up faster and have less adverse effects by driving slowly then if you just let it idle..
