Well, if they are in the cup holders of your truck as it rolls down an embankment on the side of the highway, it makes for a hot coffee shower and a ring around the inside of the cab. MESSY! I'm just now able to use one hand to stab keys after that trip 9 days ago. I was on my way to work at 6am when I hit some black ice and lost control. Did 1.5 donuts on the highway before plowing into the snowbank backwards on the opposite side of the road (sure glad that semi had just gone by!) flipping me over. Then it started rolling sideways until I ran out of hill to roll down. After crawling out and surveying the damage to my truck I feel very fortunate to have been able to walk away from it.
