Most people worry about the beginning of the trip (when should I start driving, etc?). The focus should be at the end (has the car run enough at temp before shutdown?).
P.S. I can't believe people are still repeating the old wives' tale about idling the car to let the turbos cool before shutdown. Are they deaf? Don't they hear the fan and pump going after shutdown on modern cars? My M2 does it plenty loud. My Jeep does it plenty loud.

My M8 circulates coolant after engine shut down to cool the turbos. But I still will let the engine idle maybe a minute or two if the engine oil temperature/coolant temperature is elevated.
I do this to reduce the wear and tear on the battery which powers the auxiliary electric water pump and radiator fans after the engine is shut off.
