I remember a time when police used to stop people who they thought did not "fit" into a particular area of town. This both affected thieves (and non-thieves) from poorer areas driving in affluent areas and it also affected people driving up-market cars into poorer areas (usually looking to score drugs or a pick up a prostitute or sometimes just visiting relatives/friends). This is not done as much any more. I recall getting pulled over over the years and being asked by police "where are you going?". Obviously one does not have to answer, but it gave them the opportunity to smell for weed or alcohol use and also see what was in the car (possibly prohibited or hot goods in the car)
