You have to set him up.
He has to think that cars are bad .have a car full of people come over(with the windows down) and when he comes near the car,everyone in the car is the trow a soda can with stones in it(makes alot of noise) to the ground(not at the dog).When he is startled call him to you and praise him.
After a few times he should learn that it's better to be by you then near the car.
Never tried it,but read it in a book some where.
