It's too expensive to have your dog chasing cars.
Apart from vet bills there is the ranger to consider
But in saying that...we have about 3 dogs here in my street that take themselves for a daily walk
One big chocolate staffy trots down my street and if my cat is out the front crosses to the other side
for the distance of our block and then comes back across and on his way to were ever he is going
and in about 1/2 an hour he comes back my way on his way back home...
