Harrison Ford is like one of those sports cars that advertise acceleration from 0 to 60 m.p.h. in three or four seconds. He can go from slightly broody inaction to ferocious reaction in approximately the same time span. And he handles the tight turns and corkscrew twists of a suspense story without losing his balance or leaving skid marks on the film. But maybe the best and most interesting thing about him is that he doesn't look particularly sleek, quick, or powerful; until something or somebody causes him to gun his engine, he projects the seemly aura of the family sedan."
(Richard Schickel, review of Patriot Games in Time magazine)

A car being compared to Harrison Ford in Patriot Games is a great analogy. Both Harrison Ford and a fast car show a fierce attitude with a sense of appropriate aggression at the opportune times. The main thing that makes this comparison dissimilar is the fact that a car is a mechanical machine where as Harrison Ford is a human.
