> Surveillance is generally a net negative, but it's also bad when you see people speeding around schools, rolling through stop signs, and running red lights.

Speeding and running red lights can be combated without affecting the privacy of innocents on the road. A debate can and should be had about the placement of radar traps though, many are straight off highway robberies trapping people who don't notice a speed-limit sign that is visually hard to notice.
