I had a 2003 4X4 GMC 1500 that had the auto feature. What short time I owned it I never used that feature. When the going gets tough (roads slick, rough terrain) I generally have a good idea as to when I need to put the truck into 4 hi. I could see where the auto feature would be great if the wife was driving in bad weather. Some women may not know exactly when to put a vehicle into 4 wheel drive. Hence, all of the SUV's and stuff that have 4 wheel drive that kicks in when a wheel slips. Modern technology at its best.
