yea that's probably about right. The rest of your post I pretty much agree with too.

Just in case it got lost in all the Posts I don't think we should have photo radar set to catch guys doing 105 in a 100 zone. It should be set at some point maybe 10-20 over the posted limit. Pretty much the same tolerances the cops use. And there are many places were setting it up would be an unjust cash grab (a 30km/h limit on a major downtown through road in Vancouver comes to mind. Clearly a case were the speed limit is set not for safty but to raise cash)
