Usually when it is cold outside, before I drive off in my car I would have to wait for the engine to warm. Now if I happen to be in a rush, which is usually the case in the morning, this would take 5-10 minutes out of my time depending how cold it is. Some people don’t go through that process but ever since I was young my mother made it a big deal to do so for the safety of the engine. so i do it.

I would create a new car key that would have a specific button that can warm up your engine only. It wouldn’t have to start the car or anything, just warm up the engine. while your getting ready, just after you get on your clothes, you grab your keys and press the button. By the time you get to the car and start it the engine would be warmed up already.
