I think the most bizarre thing about this story, is that it's not 'new' to hear that traffic cams / automation can catch a ton of people speeding. Like I recall them setting these systems up in various cities two decades ago, and the number of people caught in the early stages of the programs was huge then too. It's "normal" for people to drive ~10mph over the speed limit, though that varies based on things like school zones (where you dont go over at all). It's also normal for drivers to align to the speed of surrounding traffic flows. The public pushback that resulted, killed many of the initiatives. Cams were still installed, but many cities that used them tended to have restrictive conditions. This isn't 'new' tech by any stretch, nor is it a 'new' idea to be tried.
The article hints that they're allowing a 10mph wiggle room this time, but the main thing that's changed, is the public has been beaten into submission by authoritarians -- it's unlikely there'll be any civil action against it.
