Ok so here’s my experience:

In regard to speed cameras I notice if you don’t go over 5MPH you’re good, might be able to do 10 over but I haven’t risked that to check. As for the ones on 83, don’t go over 60MPH and you’re ok.

Red light cameras seem to be tweaked depending on the popularity of the intersection. Falls Road/Cold Spring and the Presidents Street/Fayette intersections don’t fuck around. Others seem to have a slight delay if you’re trying to get through a yellow.
