The question broadly conceived regards nonstandard forms of religious activity. When one considers the multitude of religions in the world, and the wide variety of religious practices encompassed, it seems there is no standard form of religious behavior. Consider, for example, a Quaker service, where a group of worshippers gather without a designated leader. The group may sit in silence for the duration of the allotted time. The notion of attending a religious service without exiting one’s vehicle may be unusual, but that does not make it less religious. It seems like an extension of a drive in movie, which was a commonplace of my youth but more rare on the contemporary scene. In a religion like Hinduism most religious activity occurs in individual homes. Some protestant Christian services fill whole stadiums with their attendees. Between these two extremes there are a multitude of variants, all of which are okay.
