And they are that high just because statistically they are in traffic for such a large amount of time.
Tells me we can change what police are and aren’t responsible for, and it is telling which ones they want to drop and which ones they don’t.
Here it's required to have a police detail at every road based construction site. They get paid overtime to sit there playing candy crush in case maybe something happens requiring them to direct traffic. So it seems like a win-win to replace them with citizen flaggers as it'd remove the cops from that role but also drastically lower cost to the city. But no, it'd mean taking what should be a minimum wage job and paying someone $50-100+/hr to do it.
And then the secondary debate is that some people see this as a bad thing and others see it as a good thing.
