Starting the car and running it for a while is the absolute worst thing that can be done. There is a pant load of data on this.
If you start it, it requires several miles at highway speed to boil out all of the accumulated water in the system. It also tends to accumulate water in your engine which, under the best of circumstances, turns
oil quite acidic and often damages internals.
In winter, after shutdown, metal cools and major condensation forms on internal metal which accumulates all winter.
I have seen one Porsche engine torn down that was virtually ruined most likely because of this practice.
