For a car my wife bought me for my birthday that she is having modified in various ways, the laser jammer and radar detector system also has a redlight and speeding camera warning system. It will sound an alert for such cameras. (She also is having a "license plate flipper" installed.)
Such cameras have no method of asking a person if there is a true emergency reason for driving fast.
From your own link:
"But the lengthy report omitted facts later reported by the Tampa Bay Times, such as the fact that rear-end wrecks at intersections with red light cameras jumped 44 percent and overall crashes at those intersections increased 10 percent compared to the previous year."
The "report" he cites in your link was from a "consultant."
