8) During the gasoline "crises" of the 1970s and early 1980s, many people asked why, in view of the gasoline shortage, such "utterly wasteful uses of gasoline" as auto racing were still permitted.

Try to construct a clear and defensible definition of waste that would indict auto racing but approve other uses of automotive gasoline at a time when there might be a gasoline shortage?
