In my comment that got this going, I said: "
you shouldn't do that unless you're willing to accept any result including you and yours getting killed by the police"
Getting shot, let alone killed, is a very unlikely outcome (although a lot more likely for your dogs, if you have any), but there are so many bad outcomes calling the police should still be avoided.
You might want to read Arrest-Proof Yourself: An Ex-Cop Reveals How Easy It Is for Anyone to Get Arrested, How Even a Single Arrest Could Ruin Your Life, and What to Do If the Police Get in Your Face; I did after a cop in my fairly small home city played a game of chicken with his car and my body. Best guess, as suggested by the book, is that he was trying to generate arrest and charge statistics; the book's thesis is that with the sharp downturn in crime, what I call the police-judicial complex needs a steady diet of "the clueless" to run through the system, else there would be widespread layoffs.
Pedestrians are uncommon here, and I guess he thought I might be an easy mark, the moment he saw me he jerked his steering wheel towards me and kept the new heading. Having learned to be a pedestrian in the Boston area, the sort of thing I'm pretty sure is not true for most of the other pedestrians in the city, I could tell his car and side mirror would miss me by a foot, less for the mirror, and successfully stared him down (probably makes a difference that while not part of the official South, this bit of SW Missouri is part of the cultural south, and my mom is Cajun).
