The comfort lies in all the things you can do: The Australian drive-in - Cinema of distraction

The drive-in is a uniquely American invention. With its need for a great deal of land, a culture dominated by the automobile, and an affluent population, the United States is one of the few countries able to support a large, thriving ozoner industry. It is because of these specific needs that almost no other country adopted the drive-in, even though most things American are widely imitated in other lands. At best, most countries have had only a token drive-in or two, ranging up to a handful, at any one time. (Segrave 104)
