How does driving on the beach contribute to ocean acidification?

Driving on the beach can contribute to ocean acidification because of the pollution a car's exhaust exerts. One car can't do much to effect the vast ocean, but everyday cars are driven along the shore and they build up from time to time. This can cause alot of pollution to the waters and sea creatures.
