These cameras are a bit of a breach of the current social contract. There is a tacit acceptance in most places that 5 over is acceptable. In fact, driving the speed limit is considered inappropriate and will often have a line of vehicles following too close. There is one person who routinely drives around me.

Quietly moving these cameras into these areas results in ticketing everyone for even going one mile over the limit. Sometimes, this just happens, especially on a hill. Most people will just let their cars accelerate and then just slowly decelerate than wear their cars down.

I am all for this tech in a school zone or in properly-designated areas.
