I believe you're talking about "The Duel." Weaver is in a little Dodge Dart, a guy driving a big Autocar truck is trying to kill him. All you ever see of the guy in the truck is his hands. Made by a talented guy named Spielberg...
No, just Duel.
Amazing it was made for TV. It could have been a thetrical release it was so good. And you see the boots as well as the hands.
