This makes me ask two questions. If who knew what? And forgiven for what? And that's where it leads me... the thought that this might be alluding to a traffic accident, or perhaps someone nearly running you over.
"motionless in the midst of motion" --a stunned possum/rabbit/deer? About to eat chrome sandwich?
Nice feelings offered here to someone who has logged a lot of miles by both auto and motorcycle. It does look a little smooth without any punctuation or capitalization, kind of like a well molded street rod perhaps? I think that aspect works well here because of the auto allusion, although often it would not. Thanks.
