Streets exist by default whenever there is a space between rows of houses that people used for transportation, either by foot, horse, carriage, motorcar, lorry, tramway, omnibus, cable car, or floater.
Recent streets (less than a hundred years old, such as are common in many suburbs where sidewalks are nonexistent) are built for cars, but the majority of streets in modern cities still existed before motorized transport was common. The avenues of Montreal predate cars. The only real "invented for, and for the exclusive purpose of, cars" type of street is the German autobahn, also known as autoroute, or two-lane highway. Street photography is usually about cities, in which it is an accidental fact that streets were built, invented, designed, wished for before the existence of motorcars.
