I was stuck behind a navigator for a long time while driving at 50mph on a local highway. The navigator starts braking so I down shift and change into the other lane closest to the shoulder. Well when I changed lanes I went to accelerate and the back end of the car slid and some how I ended up loosing control tapping the navigator and she sent me off thru the snow and hitting a nice big wooden pole. I believe the car did some spinning but not sure how much. Am still in a lot of shock right now and its been a couple hours since it happend. Today has sucked badly......
