The Talking Car. (1969)
A young boy named Jimmy almost gets run over by a car, the result of which leads to his dreaming of automobiles talking to him. Fortunately he learns the "see & be seen rules" of traffic safety from the talking cars and goes on to live a full rich life not getting run over. Phew!
the cool part, the kid almost got run over by a 69 notch at the beginning. lots of cool original mustangs from the era.
