Like I said on the first page. Even if you sit forever parked the tranny and Diff will not be warmed. So you have to slowly drive it anyways to get them up to temp. Why not just let the engine cycle the oil around a few times and let eveything warm up together? I mean while single out one piece of the car Modern engines do not need such long warmup times.
as long as you let the rpms settle a bit before that

no point in a prolonged idle once the engine has reached idle revs, and oil has circulated its go time. Keep in mind if you leave the car to warm up a while the diff and tranny are still way below the temps they need to be. Warming up the tranny properly is usually my biggest goal.

I too try to take it easy before 3 bars. Unfortunately I often have to dive into busy traffic before I can reach 3 bars. Sometimes I have to get the revs up with only 2 bars showing, but I then make sure to not reach 6000 rpm. I don't really like to have to step on it without it being completely warmed up, but it beats getting run over.

has anyone reported better gas mileage by starting the car and going without "warming up"? my last fill was horrific. and i've been doing the same since prior to break in.

That said, I normally only warm it up at idle when I have to clear off snow and ice. Sometimes it's hard remembering to drive gently until the temperature comes off the peg, though.

I recall seeing this years ago and I can't say for sure if it applies to a carbeurated engine or any engine. If you idle for more than a minute, you may as well shut it off.
In the first minute to first few minutes after a cold start, depending upon the outside temps, our engines have terrible combustion efficiency. Not only do most modern day car owner's manual recommend getting under way (while driving "lightly") immediately to help the car warm up more efficiently, but why not get some distance under you for all the gas you are burning up?
