Cameras issuing tickets to people driving 11 miles over the speed limit "on streets that are hot spots for street racing, or are in school zones, or have a high number of collisions" is where you draw the line?
One problem is who defines hot spot. The speed camera companies will gin up data showing that one road section at the bottom of a hill with a with speed limit of 30 is definetly a hot spot. Also politicians will get involved and speed cameras will be put in an area for consituent placation instead of for traffic safety.
Seconding this. If you are a private company that makes cameras for this specific use case, it is in your best interest to pull numbers out of your ass to place more cameras, therefore making more sales and money on maintenance and/or service fees.
Then in a few years you likely will find it outsourced to a third party contractor, who has helpfully worked with the city or county to place the cameras in convenient spots that just happen to generate a ton of revenue.
I'm not totally against the idea, but at least where I live these red light and speeding cameras have devolved into ways to gain revenue vs. safety just by taking note of where they happen to be placed (and not).
There also has been an overall push to slowly reduce the threshold for activation of the cameras. Started as egregious speeding, now it's 6 over. The outcome is of course exactly what you would predict: everyone figures out where the cameras are and slams on the brakes for that block only. Super safe!
