I am curious about "warming" up the car myself. The other day I let my friend drive my car (the car was parked with the engine running for about 10-15 min since it was about 20 degrees outside). He drove it for about 1.5 - 2 miles and then redlined it while merging on the highway and the car shifted at 7K. IMO it just did not feel right.
