The consensus is the engine reaches its full operating temperature at about 10 miles of continuous driving.
Something interesting I realized today is that if you go to the vehicle info - service - measure oil level, if the car is not at operating temp, the start measuring oil will be grayed out

One this advantage is that you need to be in P or N for it to work. So if you are moving you can't check cause it will be grayed out cause it's in D regardless if oil is at operating temp or not
