NO ONE slams on their brakes in Memphis. I’ve lived here for 40 years and have decided that the whole population is color blind.
In Newark the cameras went into effect on New Years; there is a noticeable change in driving patterns by the commuters entering/leaving the city - they know they’re the targets, to keep the banana republic going.
