It’s quite difficult to retroactively adjust the traffic speed, without causing knock on issues.
A road might have been designed to cope with 50, but hidden junctions, or pedestrians might knock it down to a 30. Making it feel like a 30 is quite different.
I’d personally prefer other, more polite methods. In the UK, the signs showing your current speed in either green (good) or red (too fast) are remarkably effective. I accept that speed cameras are needed when the other methods fail.
Proviso, the cameras should be blatantly obvious, with no ambiguity over the limit. It should only catch people both deliberately speeding, and not paying enough attention to spot the risks of speeding.
