>movie start with a guy getting each of his legs tied to a different car
>both cars drive in separate directions away from each other
>cut to black before he gets torn in half

All i can remember from the movie is the main protagonist running away from people who can track him with his blood, so he take out some of it and inject it into a tube then put the tube on a dog's neck. Also a girl join him mid film

Im sure the movie was made pre 2000
