Here in Washington DC we've set up many different types of traffic cameras. One side effect is a reduction in the number of negative interactions the average person has with the police. There are communities where the cops treat people like piggy banks and spend tons of time aggressively enforcing minor traffic violations. That has negative effects on trust, not to mention the number of fatal interactions that have stemmed from traffic stops. Other jobs that can be done by the police in other places are handled by Parking Enforcement, the Department of Buildings, etc.

The recent presence of federal agents and soldiers has reversed some of the hard-fought gains in trust, but my broader point still stands: more automated enforcement of traffic laws has positive effects in how people interact with the police. This effect needs to be balanced against the harms of increased surveillance.
