They seem to. Near me they've gone up on a main road and, despite still note being switched on after six months, the crazy speeders have slowed. It's on my commuting route so I appreciate that.
Except for the dimwits who cut two of them down and who were quickly identified:

my mother got a ticket in the mail, with a photo of her car, she was making a right turn, the photo clearly showed she had a green light. humans aren't even checking these things before sending tickets, or maybe they are, who knows. I appreciate the intent but we are living in an increasing police state & I'm super liberal & a cyclist
there are many roads in the NE US w/ very low speed limits like 40 or 50 where ppl routinely drive 70+. I'm so confused what to do, drive the speed limit while ppl pass me at twice the speed? & I never see any enforcement, as if everyone knows the real speed limit is 65
on some NY highways I see all kinds of devices, some are obviously cameras, others I have no idea what they. I guess it's good because it anyone commits a crime & we know their plate # or vehicle specs, it can be found, if it's on one of these highways
