The car runs rich at start up untill
O2 reaches 600 degrees (it has a internal heating circuit to help)
Coolant temp reaches a certain voltage output.
Pre set time must pass
Those 3 things are what usually run open or closed loop.
Drive it as soon as its started?
Clearly you guys don't understand the dynamics of the cylinder walls.
When cold they are a bit oval shape , when fully warm they become much more round.
The engine had no load before you put it in gear. If you drive it right after starting you risk scoring the walls because of the engine load and engine not fully warm.
But do as you will . It's your car .

In a perfect world.. this would be ideal. I even know of race teams that circulate hot water
in the engine before firing it up for reasons you mention..
but in the real world.. its just not so.. and there are many cars running around with hundreds of thousand miles that are used everyday and no ill affects. Its ridiculous to idle your car for 10's of minutes..
just start it, let the idle settle before putting it in gear.. and drive
easy for the first 10 minutes or so... waiting for x degrees on the O2 sensors, oil or whatever is not necessary... it will last plenty long without doing any of that crap... you will get tired of the car before anything goes wrong with it..
