The city of Tacoma, WA recently implemented new ALPR ticketing systems to enforce speed limits in northern Tacoma. They received so many hits, they had to build out a new system akin to a lottery for sending ticket / infraction notices.
To me, that seems like the city is entrapping its citizens to make up for a lack of revenue, when the data clearly shows the speed limit should probably be adjusted. But no, they move to develop a lottery system to send the infractions.

The problem is a cultural one. Most people interpret a speed limit of N as "I should go N+10" (or something like that). If we remove speed limits, the majority of people would end up driving at unsafe speeds. People will always break speed limits unless they are set at that unsafe level.
Speed limit cameras are highly effective at slowing cars down. They were recently removed in Ontario, and the average road speed increased substantially. The pedestrian death counts spiked in both Toronto and Ottawa this year. This is likely not a coincidence.
I prefer that people drive under the speed limit actually.
25 mph limits abound in Seattle and hardly anyone bothers with following them. The only way they are going to ever enforce that is with speed cameras since we also don't have enough police to even deal with violent crime, let alone with traffic violations.
Entrapment means the government induced the illegal behavior. An ALPR speed cam doesn't induce anyone to speed. Its not entrapment, just drive the speed limit and you won't get tickets.
