Whoa!
Yup...the reason I recall it is because on that very same morning I was in a town in central Quebec (200 miles north of Montreal) where the low temperature was also -40F.If I had been subject to a 1 minute idling limit there I would have been stranded.I let the car idle for 10 minutes before I dared put it into Drive...and I kept the speed at 30MPH for about 30 miles after I started out.
