It is very rare that I have to use 4wd... The traction control logic in the Raptor is simply amazing.
I made a believer out of my wife the other night. While coming home I was doing my normal driving in the ditches through the icy snow mix.. I stopped at stop sign with both passenger side tires in the snow and ice.. As soon as I hit the gas the passenger side tire started slipping, and the traction control kicked in. It applied the brake on spinning wheel and allowing the truck to gain speed.. Granted it was not the fastest way, but my wife noticed the truck was able to get going..
