Crime-writers (and moviegoers) are attuned to that staple of adrenalin-pumping action, the car chase. It doesn’t matter whether the pursuit is from the perspective of the follower or the followee—“That red car’s been behind me since Cleveland!”—they can be fun to write and nerve-wracking to read or watch.
Alas, chases that are little more than special effects demo reels (thanks, Hollywood), bear little relationship to how actual people would behave and strain readers’ credulity. If your characters are ordinary citizens, they’re unlikely to notice they’re being followed in the first place. If they do notice, they won’t know what to do about it. You have to find the sweet spot between over-the-top demolition-derby mayhem and dull cluelessness.
This renodadsblog post, written by two former CIA operatives, gives some tips on how non-professionals can detect surveillance. It’s basic stuff, but if you’ve been on a steady diet of The Fast and the Furious franchise or reruns of The French Connection, and you want to get back in touch with the reactions of the typical American distracted driver, here you go!
Story characters can be followed on-foot too, of course. The Art of Manliness guide on What to Do If You’re Being Followed gives common-sense advice on detecting and eluding people following you—assuming they are everyday muggers and not trained espionage agents, of course.
It all starts with being aware of your surroundings and policing your social media, two tactics your characters may—or may not—follow. Is there some reason your character is hyper-aware? Characters make mistakes (aren’t they fun?) but they also are resourceful.
