All that’s missing is a sign: "Free vulture buffet. Line forms here."
The "buffet" is a small-ish dead groundhog, newly dead. Notice the vultures include both turkey vultures and a few black vultures. Driving by, a few of the turkey vultures hopped away. Not the black vultures. My impression is that they are more aggressive around dinner or at least less likely to be intimidated by something so mundane as a car.
