Yaar that's scary more than anything. My cousins house also requires climbing a hill of sorts and I have had my car skid backwards. It is not a pleasant experience. I hate snow and ice. The worst.
Last year we had the worst black ice on the the roads and 8 cars banged into each other going down my road, then they closed the road to properly grit it... Thank god we didn't take our car out... In 2006 my hubby couldn't drive our up the road so he had to park it on the main road and walked to our home.
