Al Oft is a character in Cars and Cars 2.
Al is high on life. As an endorsement billboard in the sky for the Lightyear Tire company (proud sponsor of the Piston Cup), he loves to provide those grand images high above the track. He's just happy that his job sends him to great sporting events because he always has the best seat in the house!
A Lightyear blimp appears in Cars 2, but it is not confirmed if it's Al Oft.
