icy roads and hot wheels

Last night I dreamt that I was driving on some back road.  A nice twisty one in the Lotus but it was night or getting late and then it started getting cold outside.  And then the road got icy.  It was ok for a while but it was also getting really steep.  It was so steep and icy that I couldn't drive any further.  So got out and I put the car between my teeth so I could take it with me and started climbing up this rope with it.  It was small, like a hot wheels and I was "climbing up the road" on a vine.
