It was one of those driver vs outlaw cop movies of the late 70’s. I remember the hero driving a fast car maybe a Shelby. He got help from a black female DJ. IIRC only her lips were shown as she advised him of the Smokey situation. In the end
he crashes into a bulldozer and the car is blown up
Any idea what this movie title is? I know it is not much to go on, but thanks in advance.
