It's not good for modern cars. They less time they're idling cold, the
better. That's when they're running dirty, having poor fit between
moving parts, collecting combustion contaminates in the oil, and not
getting good oil circulation.

Give the engine enough time to stabilize, about 3 to 20 seconds, then
drive it gently. Avoid cold RPMs near redline because the oil may be
too thick to spread over the metal surfaces at that speed. Of course
it's best to not drive your car into a ditch because the windshield is
frosted over, but don't idle it warm without a need.

Check your manual for details.
