Road design, safety and Vision Zero

 "people want speed enforcement, but prefer it from a real, live officer." 

Yeah, because then they have a human that they can try to talk themselves out of a ticket; often they lean on their historical privilege to gain favouritism. None of that works with mechanical systems, which are more equitable as a result.

This is an interesting theory. I'm a little bit unsure if it's true. (I'm not even sure I believe the assertion from Berry Vrbanovic). I'd be very curious to know.

But MidTowner's conclusion is 100% correct. Expecting police to do this in person is the worst of both worlds. We do not have speed enforcement. And yet we also have the increased risk of target policing and risk to police officers (at least in Canada, AFAIK police are most likely to be injured or killed by a car crash than anything else in a traffic stop).
