Character in a car is pursued by character on foot
The expected usual ingredients for a car chase are at least one chaser, at least one fugitive, and at least two cars. Not this time. For one reason or another, the chaser is on foot. In Real Life, this would likely lead to quite a short chase and a cheery wave in the rear view mirror from the fugitive. In the movies, however, count on terrible gridlock, the chaser either knowing the streets really well and thus able to take shortcuts, being able to hitch (temporary) rides on other passing vehicles, or even just being an implacable shapeshifting cyborg from the future. Sometimes just the lead in to a normal car chase - this trope is in play until averted by the chaser getting hold of a car of their own. (Trope title from Sean Connery in The Untouchables - "Isn't that just like a wop. Brings a knife to a gunfight.")
