You drive away far enough to leave the car someplace secluded, then take the rest of your trip by foot. You know you've got to get away with no trace left behind to track you or you're a dead man. You might survive going back, but if you hide they're going to assume there's a reason for them to kill you. You make a nice go of it, though, roughing it out in the wilderness like a modern-day Daniel Boone. You only intend to keep this up until they stop looking for you, but with no idea of whether or not they're looking, you keep hiding...indefinitely. After several years of strange dream time, you wake up worried about the dirt beneath your nails.
