I bought my son a 4x4 F150.  Early in his driving career I found a patch of very icy road with no vehicles on it for him and told him to tromp the gas to see what would happen.  Of course we proceeded to spin in circles and slide into the ditch.  No understanding of counter steering in a new driver you see.  He was shook up a bit so I locked up the 4x4 and drove out of the ditch.  Lots of fun and chuckles for old dad and a good example of how easy it is to lose control for a new driver.
