My Dads Idiosity

My van driver was about to pull in my driveway to drop me off and my dad was in front of me and the driveway was icy so he didn't make it up easily and he was sliding. He popped it into 4-wheel-drive and still slid. He had to back out and across the street and get a running start to get up the drive way. Just following that my van driver made it up the driveway without any problem with a 2-wheel-drive Ford E-150
