Taking devil’s advocate here, but people claim that automated enforcement has equity concerns, privacy concerns and immigration concerns. Again, these aren’t my arguments, but:
There’s concern that automated enforcement is a regressive punishment that unduly burdens low-income motorists. There’s a belief that these cameras will be concentrated in low-income or minority neighborhoods.
The privacy concerns are fairly obvious, people are concerned the government is building a database of vehicle locations.
And the immigration concerns are that information could be fed back to ICE to detain undocumented immigrants.
However if you read the enabling legislation, a lot of these concerns are addressed through data retention, data sharing and safety standards (i.e. tickets can only be issued at 9 MPH over the limit and there must be a warning sign.)
I also think an unspoken part of the opposition is some people feel they can talk a cop out of writing a ticket, but they can’t argue with a machine.
