Waiting til the coolant up to temp is a misnomer anyway. Oil temperature is more critical. Drive any of the early 2000's Audis or, the 48 hours I drove a Phaeton W12 with an OIL temperature gauge and you'll understand. Water heats up a lot faster than oil. I drove the Phaeton in February 2004 as part of the 24 hour test drive intro. The coolant was up to 190 degrees within 5 minutes. The 12 quarts of oil took more like 20 minutes to reach operating temp. Just start it up and go....
