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.
