The current crop of vehicles generally drives quite well, even when "cold" - yet ALL the systems are happier once they get some exercise & warm up to normal operating temperatures. Over the years I've seen some extremes of damage done when the operator didn't understand the importance of this. It's QUITE uncommon & any damage is usually cumulative over time instead of catastrophic. There are exceptions of course, and for automobiles winter weather is the worst. In Northern climes almost anything can break from the cold, & treating machines more gently when cold is a partial defense.

Wow, I'm surprised by this to say the least. Ok so let me ask a different way - is it better for the engine internals, etc to warm-up the engine while parked in my driveway 10 minutes before a super short trip, like my wife driving to work? (Putting MPG aside)..
