We've all heard the idea: In winter, your car needs a little time to warm up before you can drive it. And that's why across the United States, people who live in cold and snowy places -- and especially those whose cars have remote starters -- often fire up their engines long before they start driving. Heck, they might even start the car from the kitchen in the morning, and only then start the coffee brewing.

That is very true. I have a 90 Honda that has carb's, when it is below 45 or so, if I don't let it warm up for at least a least a minute she isn't happy.....
Many people warm up their cars to get the defrosters going. Just how do you keep the windows from frosting or condensing up if there is no heat available, go down the road with the windows open?
Seriously... about it.
I've lived in many places where the temps get really low. Ever tried to just jump in the car and take off? Just how do you keep the windows clear?
Sorry, there is no myth involved, it takes time for the engine heater to start producing enough heat to defrost windows, not just outside but inside as well.
For some reason this topic has gotten REALLY popular this winter.
YES, modern fuel injected cars don't need to "warm up" before driving like old carbed vehicles. Emissions systems and moving parts actually warm faster if you turn-key-and-drive. That said, the HEATER and DEFROSTER don't. I'll take a bit of an emissions drop if it means stepping into a warm car with working defrosters.

Or, do you have another solution?
This.
People aren't letting their cars run out of some fear of what happens if you drive before the mechanical parts have warmed up. People start their cars and let them sit because otherwise you find yourself sitting in a cold box, gripping a freezing steering wheel whilst flying down the highway with frosted windows rendering you unable to see where you're going.
Me. I've got an old carbed jeep. It needs to warm up a bit before it can be driven in winter.
Defrosting the windows is another issue regardless of the engine. If it's below zero you're going to need some heat to see. To eliminate the need to idle vehicles in winter, the car makers could come up with heaters that are quicker.
