The first myth about idling for warm up time is in direct contravention of my owners manual. My manula states that, the vehicle should not be driven at higher than 1200 RPM until the engine reaches normal operating temperature.
Beside the fact that this article seems to be geared toward the commercial trucking industry, not the personal owner.

You forget one thing about idling big rigs in cold weather. When the temps drop below low teens and especially below zero that oil gets very thick when the engine is off. Park in a truck stop in 0 degrees weather and shut it down and you probably can't start it the next morning. It flat will not turn over. It may not be warm the next morning but it at least will be running.

With my four Cummins powered Rams and their properly located post turbo pyrometers, driving around town seldom required more than a minute idle time to safe shutdown temp.

Even back in the previous century, Cummins recommended not idling for extended periods as it can cause cold combustion and cylinder washdown, stuck rings and clogged injectors. Truckers let them idle to keep themselves warm at night, not the engine.
My diesel pickups were no more of a big rig then than my 5.4L F250 is now. Not even with the towing mirrors out when I'm not towing anything is it a big rig. No need to pretend it is.
Now if I could add a compressor and solenoid to sound like air brakes when I come to a stop, that would be a whole different story! :B
Post turbo properly located? I and many on the TDR would disagree with that. Post turbo is too slow to respond to what is happening.
Buy a 3pc exhaust manifold where is it tapped for the probe?
Properly located according to Cummins. The exhaust elbows on my four Cummins was bolstered and dimpled specifically for drilling and installing a probe. I have the first issue of TDR. I was a member when it was a mailing list registry before the first issue. The proper location to monitor for shut down temps is post turbo. The turbo is a heat sink and can stay hot longer than exhaust gasses pre turbo. Pre turbo is for monitoring exhaust gasses in modified engines to prevent overtemp of combustion chambers. It may be more entertaining pre turbo and necessary for bombed diesels but, it's not reliable for shut down temps.

I couldn't drive down the neighborhood street if that was the case.

If you don't mind my asking, what vehicle are you referring too? I haven't found a rpm limit in any of my owners manuals for driving before reaching full operating temperature.

It had a inline 4 cyl diesel,cannot remember what brand the engine was but I think it was probably a cummins or perkins. That engine had no idle, when started it simply went from starter speed to full duty throttle speed in about two sec. I felt sure that thing would never last the winter but 5 years later to my surprise it was still working without any problems. Seldom ever added any oil to it. Shut down was the same, full load to stop instantly. Makes one wonder if warm up/cool down is really that important. However I always do it on my truck.
Diesel generators go from asleep to duty RPM right now.

I have a $200 car with a $3000, 4000 watt boom box and some rap music cd's. It's my car, my gas, my music and I'll play it as loud and long as I want to because I enjoy being annoying! Hey! We have a lot in common! :B
