Either a villain is fleeing from the forces of law-and-order or your hero is fleeing from overwhelming danger, but in either case you need a chase scene. Any form of transportation can be used and the overall structure of the narrative will be reasonably uniform although the specifics will change in each case.
Basically the scene starts with one individual threatening another. The individual so threatened departs in haste while the first person pursues. Both need to avoid obstacles and eventually either the pursued will escape or be captured. The trick, then, is to make the scene exciting.
